Hello players and developers (I hope you see the post).
I want to offer create "Shadow ban" system for RMT-bots.
It works in following way:
if bot has "Shadow ban", he can write in chat, but only he sees his messages, and other players - not see the messages. After disconnect from server, he can't enter in a server because he was banned. So, because of the system, he will send his messages to "void", and after long time he will understand that he was banned. Accordingly, the system will reduce load for GMs relatively RMT-bots, and players rarely will see RMT-messages.
P.S. Sorry for my English. I hope you understand my idea.
