Or because they think that Bitcointalk now requires the forum accounts to undergo KYC. But that's also a type of ignorance. Maybe you remember theymos' April Fool's joke from a few years ago when he created a thread to inform people they need to pass KYC to stay on the forum. There were some users who posted selfies and screenshots of their IDs in that thread.

This is the thread I am talking about: KYC now required. My guess is that all the sensitive data has already been deleted from ninjastic.space and loyce.club as well.
