For those of us that are into crypto businesses, it is very important for us to keep safe and don't keep doing the same thing over and over again that could make us a close contact with scammers or hackers. We should not also forget that these scammers can do anything for the money.
What are you referring to when you say "the same thing over and over again"? I'm not sure how most business owners work, but I notice some of them rely on third-party payment processors to filter if the funds come from a tainted address or something similar. If you're running your own payment processor I think it's still possible to block certain users especially if you require KYC and so on.
That being said, I have a feeling that exchanges are likely to interact more with funds like that compared to small/medium businesses. CMIIW.
