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
curious. source of your reading?
based from my quick search - check this article -
https://survivorsagainstsesta.org/platforms-discriminate-against-sex-workers/maybe the OP read the item #26 here -

and if you submit KYC, maybe the site happen to search your name and she's posting on her social media channel about the nature of her work. who knows? but should not discriminate a user because of the nature of work. as long as you are getting the money legally, should not turn down their services.
