Blacklist - unfairly accused

What can i do if i'm unfairly accused of using a computer during games vs opponents?

Same as if you were fairly accused - you're pretty much limited to posting here and having people make sarcastic comments, or looking in the FAQ and discovering how to appeal.

I wrote them mail, but I will offended, I do not understand this at all.
I will close my account., thank you.

After looking on some of your recent games the mark seems correct to me. The thing I can't understand - why did you cheat on the first place? You have 8k games, CM OTB title, you are author of chess books, so why, why did you do this???

Many recent games are against cheats. Perhaps he's studying with an engine against someone else doing the same, not actually trying to swindle someone else out of a win. Who knows?

The thig is that I did not!
I had better wins and streaks before.

@Doofenshmirtz even though what you described is still considered cheating, he also did have some rated games where he used an engine very recently. And now when account is deleted I won't have an answer on my question :(
