We should be careful of having proportional bans according to the fault.
Imho, changing skills and having multi accounts, should be the longest bans -and probably fake scoring too- (e.g 2 months sounds ok, but not 2 weeks). Why?, because they clearly show a deep lack of sportmanship and trying to cheat to get some kind of benefit.
To a minimum of a ret if you don't tell your opponent you're quitting for an specific reason.
We also should be careful of having the same criteria regardless the person we're banning, which is what Nole's saying, and he's right.

If you don't add me nor send me a PM, you might see your chances reduced. Inform me about anything that might have went on with your matches BEFORE deadlines, otherwise, decisions won't be changed.
