Thread:Support/About MediaWiki:Phalanx-stats-table-exact/en/reply

The "exact" option is, to put it nicely, very stupid. (see also mw:Extension:Phalanx) If you block an edit summary "foo foo foo" with the "exact" option checked, it will check all edit summaries against that. So "foo foo foo" will trigger the Phalanx filter, but "bar foo foo foo" or "foo bar foo foo" or even "foo foo foo foo" won't trigger it! It appears that the exact option was built for blocking IPs and registered users and it's not very useful outside those two use cases, because in most cases we want regex matching.
