Gave me feedback that said I was a scammer for no reason

I never sold/bought something from him. I talked to him on discord and he was very suspicious, later I read that he scammed someone. I replied on the thread by saying that he also acted very suspiciously when I talked to him. Apparently he didn't like that even though there was proof of him scamming the other guy and decided to give me feedback saying that I was a scammer.
after I caught on to him and his plans of trying to scam me, he blocked me on discord.
This guy is a piece of filth, never ever deal with him.
