First, a bit of backstory. Recently, I accidentally ruined Jayfeather's round. He wololoed me, then, when it wore off, I missed the fine print that said "You've forgotten the past ten minutes."
Now, in fairness to me, it was quite hectic and that bit was in a different font than the main warning. I did wonder if I should forget what happened, and checked the wiki, only to find no info on the Wololo Staff. I thus assumed it worked like a normal mindslave, which, as far as I knew, didn't get amnesia. But that doesn't change the fact that I ruined his round.
Anyhow, I know the pain of a mindslave gone wrong, and I think it would be eminently reasonable to attach an automatic penalty to failing to play by the rules. Obviously, one currently exists, but intent is taken into account. I'd argue it shouldn't. If nothing else, it's incredibly easy for folks to lie, especially about passive resistance. The ban shouldn't be terribly long: Probably 1 day for the first offense, with a week or more for each repeat.
This way, players would be far more compelled to cooperate with their masters. No playing dumb, etc.
