Masters on this game are playing this game for years. They know if the "two" teamkills are on purpose or by accident. They know if players try to take advantage of that 5 kill limit. Oh btw i remember this:
Seriously, you're talking about the same shit over and over again. the answer is obvious, isnt it?
You don't kick someone when they say something restricted by rules, you first kindly ask to stop and explain that it's restricted. if it's not helping, you mute them. if it becomes repetitive and the player tries to avoid muting system, you ban this player.
For masters, especially tuta:
you guys are masters for a reason - you keep the server clean by acting professionally. the server is popular, it's not a private vaq-like server where admins can do whatever they like, it's a public server with some rules. I guess you guys have your internal forum where masters have their rules explained but even without having access to this place, any master on rigatoni should understand that professionalism is the first thing which they should stick to while acting on the server/forum. professionalism is the thing when you dont put your own interests higher the main server rules, when you don't act considering your emotions towards the person.
