Fair I agree with the spirit of what you said, banning everyone who insulted someone would defo nuke the server and to extend I would be even OK with what Marth says althought I would highly question the psyche of the invidually that does it so often.
The core issue, however, is beyond his behaviour being defacto against the rules, it is the fact that he as a person is vile. He is a manipulator and has narcissistic tendencies. Hypocrite who tries to remove people who he dislikes. He did have hand in removing Sarissa, now he is trying Kaiser, I will assume there were others and there will be others he will try to get removed on his behalf on some rule technicalities. So you can clearly see that with him around, we will lose players faster not only by his in game language, but also his active vindicative behaviour on these forums. Thus removing Marth can only result in the server seeing healthier numbers.
