So votekick >abuse< is practically allowed?

[Bixby]

Any vote-kick for harassment or cheating needs to result in a suspension from the game.

That'd make it too easy to both ruin a dungeon run and get people who kick you for it suspended. Just be careful about what you say (or say nothing at all) while you're getting everyone killed over and over, then play innocent & confused when they vote kick you. As an added bonus, since every kick results in a suspension, you'd know it worked, too, since you're not getting suspended yourself.

Automatic investigation? Maybe. If they get enough (well-trained) GM staff to make that feasible. Automatic suspension? Not so much.
