i know the tk punish level was raised to reduce people being accidentally banned due to people doing stupid things. But i knew there have been several instances where people have gotten scores of up to -30 and they have not been kicked, when they have been getting punished. is there any way to lower it slightly so people can't get this far?

Agreed. Recently there w as a clan on our server. I believe it was on the 5th and they were the [bADAZ] clan. They repeatedly tk'd for about 10 mins before they were removed.
