Nice to see people are checking this out at least. As for how long they would last, maybe 1 month for first offense 3 months for 2nd etc.. ( same as ban length, it would be placed on to their account after they are unbanned unless it's perma of course).

I'm sure they would be able to change their ways after this and if they still have a red name after a few months then I doubt this will happen.

Any other issues on the idea?
