My account is blocked due to another person

My account "Предвестник Хаоса#9418" was blocked because I was on a server where some person violated the rules.
I have nothing to do with this violation like many others.
We refuse to pay for the sins of others.

I didn't violated anything. And did not show activity on the server. I just said "hello" and that's it. All other activity I conducted outside of Discord. I have plenty of other things to do as well.
And now you cut me off from a friend. He was my friend on a blocked account. Now I can't communicate with him because I don't remember his nickname number.
