I mean I could have used the GDPR (still a thing in the UK, at least for now). But didn’t see it as worth it. It really wouldn’t be worth the risk selling data that was deleted from a GDPR request.
I don’t know that they’ll risk using the data from deleted posts/comments though anyway. Most comments and posts will be deleted for a reason (moderation, or otherwise mistakes) and as such, likely isn’t going to make the best training data really.
It’s far easier to just sell the live data and be done with it.
Ah, so the kind of crypto bro, that instead of a fistbump, does a diffie-hellman key exchange instead?
