Mad at Meta? Don't Let Them Collect and Monetize Your Personal Data

If you’re fed up with Meta right now, you’re not alone. Meta tracks you across millions of websites and apps and its business model relies on your data. If you want to limit Meta’s ability to collect and profit from your personal data, here’s what you need to know.

Online behavioral tracking by third parties—entities you don't see and didn't consent to share your data with—makes the web less safe and secure. Privacy Badger blocks that tracking....

@eff

Or just delete your account. I did.

@Professor_Stevens @eff

You don't need to have a meta account to be tracked by meta.

@rzeta0 @eff

Deleting your account is still a better impediment than fussing with privacy settings. Until you do, you're still an asset to them.

@Professor_Stevens @eff

Yes, if you log in then they know who you are.

I don't have an account on Facebook Instagram whatsapp etc etc

I sadly do have one on Google and would love to get away.

@rzeta0 @eff

Precisely. They know who you are, what you did, where you were, when you were there, what OS you run, what kind of computer you're on, what browser you're using, and maybe even your typing speed, just from logging in.

But worse, they have a record that you used their system. You become an asset Zuck uses to sell services. Without an account, they have none of that, and he loses his most precious inventory item: one of us.

@rzeta0 @Professor_Stevens @eff

Came here to say this. My guess is that they can maintain a digital biology for everyone who’s ever used their service without retaining any actual submitted data. And they can use that user makeup to track people across the internet long after someone has “deleted” their account.

@bbonkers @rzeta0 @eff

But when you delete that account, you remove yourself from their inventory of active users. Without those, he hasn't got the assets that make Zuck valuable to others.

@eff @jdarnold Number one trick: stay off Meta sites.

@mlanger @eff @jdarnold

Their tracking goes beyond their own sites.

@rzeta0 @eff @jdarnold Clear cookies when you close browser tabs.

@mlanger @eff @jdarnold

Fingerprinting doesn't rely on clearing cookies.

@mlanger @eff @jdarnold -

Number one trick: stay off Meta sites.

Number two trick: they will track you even from sites that are not their own, so install software / adjust settings to block them from doing that.

Here's How Facebook Tracks You When You're Not On Facebook

Mark Zuckerberg seemed uncomfortable answering questions about how Facebook tracks you when you're not on Facebook. We went to Facebook's website to find out exactly what's happening.

BuzzFeed News

@johncarlosbaez @eff @jdarnold Fine. But if you don't have a Facebook or Instagram or any Meta product account AND you reject cookies on websites and automatically delete cookies when you leave a site AND you're not dumb enough to click a Facebook like button or go to Facebook/Insta for anything, HOW CAN META TRACK YOU?

Facebook isn't free. The users are the product. If you want to use Facebook, YOU will pay for it.

Don't use Facebook. Period.

@eff I did it. it was weird logging into facebook after so many years. Apparently Dean Cain had like a post by me from 9 years ago.
@eff Many of these steps don't matter, because it's just a user facing thing. You can toggle off this or that, but it's not actually off behind the scenes. Max tracking and surveillance always. Some extentions help I think, so that is what I have done, despite not having a fascistbook account.

@eff

Just read about this from John Oliver, done!

@eff

Thank you!

I also found "encryption and credentials" under "security" on my Android. Unbelievable how many corp crap is there. Is it safe to turn all that off?

@eff Saving this article. Appreciate the help!
@eff Agreed. I have now left facebook.
@eff Looks like I did even better with this little "trick" of holding their apps icons until they started shaking and that little menu popped out - then clicking "delete this app" 😏
@ati1 @eff but it doesn't delete your account.
@wanderingmagus Of course not. But I did it also myself. Apart from Facebook account cos I want to keep Messanger at least for now and for not so important communication. I hope they don't get too much data from my account I do not log into at all (apart of Messanger with no location data, no mic, no camera, no photos). Guess it works because now if I really need to buy sth i have to switch back to google for a moment to even get any good offers based on my search querry 😆
@ati1 You could consider Signal as an alternative to Messenger. It's actually private and used by journalists and activists all over the world!
@eff Easiest: Give Zuck the finger. You don't need any of his crap, so get off Meta shit asap.
@eff I got my Facebook addict father to apply these settings. After he watched the John Oliver episode.
@eff I don't allow Meta on my phone at all
@eff Don't forget Facebook Container
@eff There are many ways to make yourslf less valuable to Meta. The best is to close or stop using your account!
@eff What is that domain name 😂
I'm so glad I was exempt from all these steps because I don't have any Meta accounts 😌
#uBlock, Privacy badger and Facebook container seem like the bare minimum needed to survive on the modern internet now.
