I suppose it's a good idea, but if you spend ten minutes in general chat you will see how many people make multis as soon as their warn level becomes a problem. If you increase posting time, I think you will see many more multis here. That's just my opinion.

good suggestion imo, i think something like this exists already, but that would be a good way to make the warning system more serious.
but i would start it at 20%
