And besides the trickery I think you'd be able to downvoat them from their comment overview anyway with it just being a style thing. Hopefully an option is in the works or at least being considered. One workaround to disable it could actually be to raise the CCP limit to whatever the maximum is, which is hopefully something impossible. Then you can hide the buttons and even if people restore them they still can't downvoat.
As for what the limits should be, I'd say stick with the site wide 100 for now (unless there's already bad behavior with it) and consider it once there's more users. Maybe 20 would be a good starting point and if that turns out to be too easy raise it by tens. Although I'm not a moderator of anything and it could be different for any sub for all sorts of reasons.
