this is typical behavior of scammers, can you post a photo of him blocking people's account on discord?
I was blocked yesterday on discord:

this is typical behavior of scammers, so I have already left negative feedback on his account and I urge people not to use his exchange.
there are some users who are using Unnamed.exchange signature, I wonder how to proceed? do they not know that Unnamed.exchange is scam and do they get paid by Unnamed.exchange?
