Requiring "logged in users only" to edit and "turning off" commenting should cut down drastically on vandalism. But if that isn't what you want, understand any platform with such open borders will have those take advantage.

But I'd love:

Admins able to have an admin watchlist for troublesome users or IP addresses that can be cross-referenced with other Wikis. To find troublesome users who migrate Wikis.

A watchlist/flag list, a way to avoid toxic users by auto hiding their responses (before they even get to your wiki, why wait when you can see the trouble they did somewhere else first) and keeping them on an admin or staff list to see toxic users in a community or cross-community.
