Why don’t we emphasize this? We do not require KYC verification, but our partners may request it in rare cases when illegal funds, flagged as suspicious, are detected.
That's just the thing: Everyone interprets illegal, dirty, and suspicious funds differently based on rules that aren't public, and service providers tasked with creating such "rules" make them up on the go and don't even share what's allowed and what isn't with their partners. You and your crypto are suspicious, thus, we will confiscate your money. You will have to tell us everything we want to know about you and how you got the money, but we will not tell you what's wrong with it or why we are asking.
How is this information not public? All exchanges have terms of use where everything is clearly described.
Why should one report to someone who just shot at you?
Do you understand the responsibility of companies when they are audited by regulatory authorities? For example, Binance will not talk to you at all; it will block your account and issue a form to fill out. If the completed information is not provided with full clarification, then goodbye.
You are now trying to defend those who take a very small percentage and have no evidence regarding the origin of the funds. In this thread, an example was given about Exolix, which has a large number of daily transactions and withheld users' funds. So read their topic and see how many of those people there are—just two! And what proof do they have? There are no concrete pieces of evidence, just words. Don't you think these are just trolls from competitors who want to tarnish their reputation?
