@kkarhan @kaia @verbraucherzentrale Is it though? Under EU law e.g. Youtube checks IDs to see if the users are definitely not kids (it can be omitted, I used a PSC card to send some money to a youtuber and that was enough to prove I'm an adult, weirdly though), proving the authenticity for having a mark that your name is confirmed (I assume this is all about that, I haven't been using Twitter for a while and only under a pseudonym anyway) might be a legitimate reason to check all of that data.

I mean, the questions is – you say that this is illegal with a lot of confidence and certainty and I wonder why, do you just think it's probably illegal or you have something on mind?
