Probably also they selling your ID. proof of Identity + Selfie + proof of Residenz
Uploaded KYC ID documents + selfies and address data are sold with large quantities on the darkweb, which are probably collected via scam projects.

This is not a new thing, it has been for years and has been happening even anyone thought about Cryptocurrency. There used to be lots of fake sites even till today and what they do is to sell the info of those that registers or performs activities on their site, they will and sell it on the dark web. Thats why you should never give out sensitive information about yourself to anyone you meet online, always avoid sites that ask about you.
