Even if this was real, I think it’s irrelevant. If you make a public post, then that’s what that means, it’s public. What happened to the saying that once uploaded to the internet, it’s there forever? I always thought this was common knowledge. To prevent these things, it shouldn’t be possible by design. That’s why in Lemmy and Mastodon, the fact I can click anyone’s username and see their entire post history is insane to me. Why there no option to make that private, and why the hell is it public by default?
The same people crying about possible data scraping are the same ones who see zero issue with all your profile data being completely public to any possible random internet query.
