The countervandalism network is an official, semi-formal collection of channels on the Freenode IRC network.
Bots in these channels list suspicious edits to selected communities, based on criteria defined by the community using the channel. Each channel has local operators and users, and is managed by a volunteer group of staff selected from the Countervandalism IRC community.
Other more topical FANDOM channels may exist that only report for one wiki, you should check out your favorite wikis' project pages to see if they're involved in that fashion.
