Hi,
My name's Sam and I'm a Product Manager at the Wikimedia Foundation working on the Moderator Tools project https://www.mediawiki.org/wiki/Moderator_Tools. As part of the research for this project I've been exploring anti-vandalism bots in use on different Wikimedia projects, but haven't been able to find any centralised list of such bots.
So far I'm aware of ClueBot NG (en.wiki), SeroBOT (es.wiki), and Salebot (fr.wiki, pt.wiki).
If you know of any other anti-vandalism bots (i.e. bots which automatically revert edits which are identified as vandalism according to some rules/algorithm), please let me know! I'd also love to know if you have any thoughts about their effectiveness.
Thanks, Sam
