Leaving aside the title, which is directly false, and you only have to see the quote that the OP himself puts, I imagine that those who have not deposited the satoshis from the Sinbad campaign in a CEX like Binance will not have had problems: those who have sent them to a bitcoin ATM or have bought gift cards or deposited in a casino of those advertised on the forum, for example (I am obviously ignoring those who simply HODL).
Some user included me, received message from Binance that we recieved fund from Sinbad signature Escrow address and we have to give cleanliness that from where we recieved fund and what is our relationship with address owner.
Working for a mixer and depositing what they pay you in a CEX, even more by doing it just like that, without going through a previous coinjoin for example, I don't quite understand, I would appreciate it if someone could explain it to me.
On the other hand, Royse777 is right to consult a lawyer before making any other move, as things stand.
