Now, ripping that _user_ generated data from the website this way without justified (justified = platform user agreement + legitimate interest) purpose or intent or even agreement and storing / distributing / processing it is the epitome of a GDPR transgression and borderline criminal at least in the EU (saying this as a EU citizen). They are liable. I wouldn't touch that dataset with a 10 foot pole. And I would even less brag about it on Twitter, things we do for clout I guess... :)
I have no stake in this thing, it's just to emphasize that statements like this are what get people and businesses in big trouble. Stay safe! Archive only your own data or data you gathered legitimately. Take the rest up with a lawyer or ... read the laws.
