That's not really how it works. Communities in FANDOM were meant to be editable by everyone, not by certain groups. If you really suspect repeated vandalism, you could contact a VSTF to watch your wiki for a while, or maybe perhaps an enabled AbuseFilter and let the VSTF set it up for you, instead. You should read this section of how to deal vandalism. There's not really quick fix of how to stop vandals, but there is a quicker way, and you should hold these chips: revert, block, ignore.

Another great idea is to disable anonymous editing in Special:WikiFeatures. That way, no anonymous users edit in your wiki. Maybe, contact staff via Special:Contact/general and let them give you advice.
