The AbuseFilter has been re-purposed to not only look at abusive edits, but also be used as a means to stop things like test edits. The names of the components of the software (abuse log, etc.) have caused a lot of confusion and hostility, esp. as they often are simply inaccurate for the filters being used.
The extension should be renamed to something less inflammatory. Suggestions include "ActionFilter" (which keeps the AF initials) or "EditFilter."
