How does 4chan get your data to make fake posts?

> How do they do this?

This isn't happening.

> How is the data obtained?

The web is a big plac, but you're spending too much time online andhaving repeat interactions with the same media. You need to spend time away from screens and with other people IRL.

> Is there a way to block it?

YES! Never visit 4chan again and spend way less time browsing aimlessly online, and not only will this problem stop - but many other issues in your life will likely resolve.
