Some times a filter happens to have some false positives. The users who monitor the Special:AbuseLog should be able to mark such entries in the log as being false positives so that other reviewers don't need to review the edit again. Besides, if the extension keep track of log entries which are false positives the message
Filter hits: NNN hits
could be changed to
Filter hits: NNN hits (MM false positives)
and the after the "Hit count" column there could be "False positives count". This would give a better sense of the quality of the filters running in a wiki.
