If we're due an influx of censorship-loving cucks because Plebbit faggotry finally affected them personally, let's give them what they're after. Here's my idea...
Allow them to setup their subverse as they see fit. Give them an option to have the sub marked as a "safe space" where they can ban/delete/whatever as much as they want, and anyone going there knows that it's a "safe space" for whatever they want that sub's particular topic to be.
Then at the system level, make it a hard quarantine zone. Anyone who moderates, posts, comments, or up/downvoats in that sub is prevented from interacting with any subverse that's not marked "safe space". They can't submit anywhere else, can't comment, can't vote.
Moderators of "safe space" subs will be permanently quarantined. Users can be let out of the cage only after, say, six months of no participation in the "safe space" censorship gulags. And Voat admin get the power to manually mark a subverse as a "safe space" if it's found to be going against the ideals of Voat (i.e. they start banning/deleting because of feels, etc.).
Basically, they can either assimilate and become regular goats, or they can protect their pweshus feewings. But if they choose option 2, they have no ability whatsoever to Plebbit-ize the rest of the site.
Oh, and "safe space" subs are hidden by default unless you specifically elect to see them.
