-This extensions implements everything related to GNOME Bugzilla.
+This extensions implements a basic AntiSpam method. It works by blocking using
+words or regular expressions.
 
-Recommend not to use this extension anywhere else. The functionality is really
-specific.
+It doesn't handle comment nor attachment spam. This could easily be added but
+as there's no such spam currently on GNOME Bugzilla this hasn't been
+implemented.
+
+Note: The extension is aggressive. It assumes that there are no mistakes. It
+*will* ban users. It *will* call them a spammer.
