There are some fedi scrapers.
At least some people on Mastodon really noticed it after they managed to look up their name on chatGPT

At least for a while (dont know the current case) some people bragged about being able to scrape fedi content or something

Dont know it some of the scrapers are gov spies tho

Gonna edit this after finding the saved messages that support my comment, needs probably a while ;.;
