So of recent many people got there withdrawal suspended due to a potential poisoning address attack after receiving payment for rainbet campaign managed by Hhampuz, this is common with KuCoin exchange users
How did you get that information? Is there any place the exchange mentions about blacklisted transactions?
All I see is two similar addresses show mempool show a warning like it could be an attack but if it's actually two different addresses, then there should be no problem with that. Certainly, exchange's blacklisting seems weird to me.
I agree, there doesn’t seem to be any report of a lot of accounts being blacklisted or suspended just because of that suspicion. It’s understandable if the system flags it and puts a temporary suspension while under investigation. But once they see there’s no real intention to hack or abuse the system, they usually reopen withdrawals.
I think OP is just being extra careful, but without solid proof of a violation, that kind of fear shouldn’t really be there.
