This was one of the guys :

You can see in his chatlogs he says something like "lets ban him".

I couldn't find any of the other guys because their names were to vague in the chat logs (one guy called killer and one guy called super).

Looking at your chat logs though, it seems that you incited the argument that caused a voteban to go off. Threatening people by saying "If you dont stop blocking me I will get an admin to ban you" probably isn't the way you should talk to people on servers. Maybe be a bit more polite?

Either way, they shouldn't have abused the voteban system to get rid of you. Do you remember any of their names?
