My Twitter account is currently locked and I don't look at it, but I'm hard deleting it this month. If you have a Twitter account you don't read, I also recommend full deletion before Nov. 15. Here's why.

Twitter has their TOS now in an unusual state https://x.com/en/tos with two copies of the TOS printed one after the other, with a notice the new TOS goes active November 15.

The major difference I see is starting Nov 15 they give themselves explicit rights to train AI models on your posts.

X Terms of Service

Read X's Terms of Service to understand the rules governing your access of all Twitter services.

Concerningly, the wording of the new TOS implies they can / intend to do AI training even on accounts marked "private". The TOS says they will respect your choice to "limit distribution… to a restricted community"— but only in the EU version, and per my read (I am not a lawyer) this applies only to "mak[ing] content available", not training. I could be wrong on this point, but I am choosing not to take the risk.

If you have sensitive content on a private Twitter account, think about this hard.

My reading of the old TOS (again, not a lawyer) is Twitter loses its copyright license to your posts when you delete your accounts. I worry Twitter might have already used my posts for AI training ("grok" must have been trained on *something*) and I don't think Elon Musk follows the law, but at least by deleting, if courts someday rule AI models are derivative works needing copyright permissions, Twitter won't be able to say "good thing all these dead account holders gave us explicit permission"
(One unanswered question: There is a checkbox granting permission the rights to use "your posts" to be used for "training and fine-tuning" "with Grok". If you uncheck this box, will Twitter refrain from using your posts for training, even after the Nov. 15 TOS update? On the other hand, will this box still exist after Nov. 15? Or will this box still exist in two years? Anyway whether you delete your Twitter account or not, I suggest unchecking this box.)
Following my Twitter account deletion, you will be able to contact me on Mastodon. If you don't understand how to use Mastodon, simply ask for help on Mastodon using the Mastodon account you are using to read these words now, and someone will explain it to you three times.

UPDATE:

After the thread above, I spoke to a number of people who said "well, instead of deleting my Twitter account I'll just mass-delete the posts".

I have spoken today to two separate people who wiped their Twitter accounts via tools like Redact, & today found the posts un-deleted without their permission. In one case tens of thousands of posts were un-deleted.

If you've previously deleted Twitter posts, I recommend verifying they're still gone. And also, I recommend deleting your account.

@mcc
Something else pointed out re: the new tos is that all disputes are to be handled by a judge in a single judge district in North Texas who has a whole ton of Tesla stock, and this far a pretty heavy tendency to go with whatever musk wants.

This is not a location that has anything to do with twitter or Tesla outside of that.

I don't think this is relevant to your situation, but seemed worth sharing.

Musk steers X disputes to conservative Texas courts in service terms update

Although choosing a venue is not uncommon, northern district stands out because it’s not where X is located

The Guardian
@mcc I’m afraid you don’t need to have a Mastodon account to read that post, making it less ouroborical than intended
@mcc if I get them to explain how to use Mastodon three times in front of a mirror in a dark bathroom, what happens then?
@mym Well, it means you're trapped in a dark bathroom with another Mastodon user. You'll have to decide how you feel about that

@mcc

The problem of warning about a failure of the system that warns is similarly amusing.

@mcc if you wish you can also join the bridge to bluesky so your posts reach that network too

@mcc ugh, I just tried logging on for the first time in two years to delete my account - apparently I had 2fa set up with some authenticator linked to a phone I no longer have.

Saved codes? Nope. Sigh.

I really don't want to deal with "support" on this

@mcc yeah I feel like those are some pretty important questions to get answers for
@mcc what is the downside to checking the box?
@mcc Thx for the reminder ! Long time due ! #ByeByeTwitter
@mcc I can imagine an entire prompt engineering special skill evolving to extract private information from AIs trained on unsuspecting users' data. Good thing Xitter's AI bot is fully self-driving.
@mcc Btw, fun copyright fact: in some countries, copyright includes a right to take back.
@mcc I have a feeling that even if you try to delete yourself it won't actually remove your data from training at this point
@mcc This is why so many tech companies dislike the EU
@mcc obviously not going to defend Elon/his actions, but you *can* opt out in settings > privacy and safety > Data sharing and personalization > Grok
@dngrs For how long will this opt out be honored?
@mcc @dngrs it won't after November 15th. Thats kind of the whole point, opt-out is going to go away.
@GabeMoralesVR @dngrs Do you know this for a fact or are you assuming?

@mcc @dngrs It's what's been reported across multiple tech outlets that I've seen reporting on this, eg: https://tech.co/news/musk-sneaks-in-x-ai-training-clauseand-no-you-cant-opt-out

EDIT: Note, I don'tk now if tech.co is legit, it's just the first example I saw when I went to grab a link saying this. I'm simply using it as an example of such reporting.

Musk Sneaks in X AI Training Clause…and No, You Can’t Opt Out

X has updated its T&Cs and eagle-eyed users have spotted a now sweeping rights grab that means all content can be used for training AI models

Tech.co
@GabeMoralesVR @mcc oh wow. Time to poison the AI well with more unhinged tweets I guess (I can't easily delete because I rely on (Long) Covid information which is pretty rare outside of Twitter, sadly)
@dngrs well @mcc's follow up toots have me questioning the validity of their reporting, and whether or not it's just an interpretation that hasn't been clarified. But either way I'd urge everyone to get off twitter asap, like even more than normally.
@GabeMoralesVR yup - I wish I could leave. The only content I still leave on there these days is a clown gif to insult nazis/ai bros/inept politicians/etc
@GabeMoralesVR @dngrs A person with a website can just say anything they want. Come to think of it, a person with a newspaper printing press can just print anything they want on it. With any form of media, when a claim is made, you need to check to see what source they cite. If the source is some anonymous entity and you're supposed to just trust they've checked it out, then they should say that.

@mcc @dngrs thing is, unfortunate I don't think that line of thinking necessarily works in this instance, because the only possible source can be the twitter TOS, which then becomes an interpretation thing, which then becomes a "test in court" thing. And that's probably all by design. My inclination would probably be to at least consider the worst-case interpretations in this case.

I saw people citing lawyers when reading about this, but again, that's an interpretation until it goes to court.

@dngrs @mcc Does an opt out mater if they give themselves the right to ignore it?
@dotproto in theory one could sue but, eh, better not to trust anything Elon for sure.
@dngrs I wouldn't trust Elon to respect the choice, or the laws.
@mcc
@mcc I used an automated app to scramble all my old posts and likes and such before Musk completed his purchase of twitter. Unfortunately I don't think those will work anymore thanks to the API access stuff. Best of luck leaving twitter for good, that place sucks.
@GabeMoralesVR @mcc You can delete all Tweets by feeding a data export to this script https://github.com/lucahammer/tweetXer (I wrote it because I was annoyed.)

@luca @mcc doing the lords work 👍

@luca @GabeMoralesVR @mcc

Hey thanks for this! I was wondering if there was a way to mass-delete tweets.

The only reason I haven’t deleted my Twitter account is so that some rando Nazi doesn’t co-opt my artist name. It’s set to private, but if privacy is losing a lot of its protections it’s time to nuke all my tweets, too.

@luca @GabeMoralesVR @mcc Thank you! This is on my list todo before Nov 15
@mcc i don't really mind if the AI gets trained on my posts

@cloudfruit @mcc I do. Training data on posts doesn't just affect the person whose data is being trained with. What if you posted incorrect info? What if you hold disgusting views? That shit gets fed into the torment nexus machine and destroys the internet. It's not just about YOUR data being trained. Training AI on twitter is going to have a disgusting ripple effect on what "truth" is. It's going to obfuscate so much crap.

Twitter has to be one of the worst sources to train with. Awful.

@GabeMoralesVR @mcc what is truth now and by whom is it defined?
@cloudfruit oh shut up
@GabeMoralesVR you’re just a lazy thinker who wants to be “right” about things. Expand your horizon and apply logic universally ;)
@GabeMoralesVR @mcc also why immediately shut the conversation down? Have you no capacity for debate? Are you scared of having your beliefs challenged?
@mcc not contradicting anything you're saying, but i have zero confidence that they won't scrape the contents of deleted tweets (which remain in their db), deleted or private accounts. even if it's illegal, they will do it anyway; there are clearly zero ethical guardrails left in place there and they're already openly ignoring multiple laws.
@jplebreton Oddly, the Facebook TOS is clearer and gives better protections on this specific point.
@mcc how do you expect or trust Twitter to delete the content and not just transfer it into a database to use at their whims?
@Ulan_KA My goal is to deny Twitter a grounds to later claim that they were doing such things legally. I am aware I cannot really control what Twitter actually does.
@mcc I'd need a bot to edit every tweet ever into gibberish and *then* delete the account
@mcc
Mine has been locked for a year or so, unused longer than that, but I finally logged back in and requested deletion.
Past time.

@mcc if what has happen does not help that wont help either.

Tumblr started doing ai shit and people is still quite active there

@mcc i just stopped using mine one day, but what I'm hearing is that I should post a daily lorem ipsum. Except I'd rather just make him continue to pay storage fees for my worthless account.
@mcc
Can you imagine the LLM trained on Twitter content?
@inthehands

@mcc I'm going to keep my account open because I don't want some scammer registering my handle on there so the "@dmarti" links go to a shitcoin or whatever

(but all I'm posting these days is "how do I get support for MetaMask" to see how the bot scene is developing. They're still pretty basic, not even LLM backed as far as I can tell)

@dmarti @mcc Same reason I'm holding onto my handle there - there have been several folks wanting my handle (they've offered money) and I do NOT want them to have it.
@mcc thank you!
I didn’t realise I hadn’t “deactivated” it yet.
I have no idea if that deletes it in 30 days but eh, that’s my best guess
@mcc I'll have to try again to delete it
