I've been reading how Coinbase shuts down sex worker's account. I was wondering how do they know account is from a sex worker? They probably don't use your real name in sex work so even if they pass KYC Coinbase can't know unless they do a research on them.
Payments are anonyoums. I don't understand
According to their user agreement they do not allow these sites to receive and send funds from coinbase. They do not deny these workers to open account on coinbase but they prohibit them for the use on such sites where sex workers work. So they will not freeze/lock your account unless they find that any fund is received or sent to any of the adult website.
