Twitter seems to have removed the new policy to ban accounts linking to competitors.

here is their page in the internet archive's wayback machine: https://web.archive.org/web/20221218183504/https://twitter.com/TwitterSupport/status/1604531261791522817

I admire that they have the courage of their convictions...

@brewsterkahle Account ban removed, but linking is still blocked. Possibly planned all along.

@shandrew hum.

My twitter profile has a link to mastodon, and is still visible to me: https://twitter.com/brewster_kahle

I am a small fish, so maybe this only applies to others.

@brewsterkahle Looks like mastodon.archive.org escaped whatever matching they are using to block the URLs. Most mastodon links get the "unsafe link" warning if you try to click on them.

If you try to add one of these urls to your profile, you get "Account update failed: Url is considered malware"

I hope you guys are keeping track of all the dumb things he tweets and then deletes. It will be important to have a record of all this.

@karstenbondy

always ways to be better, but we are pretty good at it.

@brewsterkahle you guys are the best there is. I have nothing but the highest admiration for what you do. You're my Amazon Smile donation.
