Idk man, $5 once, for voting rights for as long as you participate?
I get your point, but it's a pretty quick filter for trolls. Few are tossing five bucks for the privilege of fucking shit up when they can do that other places for free.
I'm not casting my vote yet as there are other means of gauging someone as an actor deserving* of voting rights in an instance (account membership, length of membership, x period of not being a shithead/having mod actions performed, etc.) that haven't been fleshed out here, but if that is too difficult or fraught to be effective I will support a small fee for voting rights (while fighting tooth and nail against making this a pay-only instance afterwards).
*'Deserving' may raise some hackles, but keep in mind this isn't a country in a real sense. Instance migration is a trivial action. If you feel you're disenfranchised in some way by whatever vetting for voting rights we land on, pick another instance or spin your own.
