We’re considering setting up our own instance as well, but that’s a bit above my IT skill level. Thanks for the suggestion!

Perfect, thanks! Yes, of course ban evasion and upvoting yourself would be against what we want as well. But if the “pretending to be multiple people” thing is under our control as community moderators, that’s exactly what we’re looking for. Pretending to be someone else is a core part of our roleplay group ;)
