Problem: There is no clean way, with AbuseFilter, to detect an edit is a revert. Which is important, several long term abusers having for habit to revert editors edits as a way to harass them.
Proposed solution: Create a variable revert (if possible with the username of the author of the reverted editor) in AbuseFilter.
Who would benefit: Abusefilter editors, harassed editors, everyone.
More comments: This change has a dedicated phabricator ticket (see below). From what I understand (thanks to Daimona Eaytoy explanations), this task is currently stalled because a change is needed in the mediawiki core code, regarding when abusefilters are processed, and when an edit is marked by mediawiki as a revert.
