This plugin makes it possible to exclude users from specific topics.
Moderators have the opportunity to manage them naturally and can not be excluded, provided you have the right to do so.
Users can be added via the Edit->Advanced button under the Exclude users from this thread. Users can, of course, also be removed from the list.
All contributions and topics are removed from various collections, be it the last activity or a user's contribution list. The topics can not be called by the direct link.
