I'd like users to be able to appeal signature bans. I know, some strikes I've deserved, but sometimes I've recieved strikes and haven't got the chance to read a mod's thoughts on it, much less change it.

So like, when you get your fifth strike (IIRC), you can appeal it after some time, and then you get a final chance. You screw up again and then you really are sig banned with no but's.
