Comments "disappear" if they contain words of the banlist

Sometimes comments are unpublished but not added to any moderation queue. I think it happens if the following pre-conditions are met.

• Comments are not pre-moderated
• The user submitting the comment doesn't have the "direct flag" permissions
• The comment contains words of the banlist
• The abuse_threshold is >1

I think there is an error in _watchlist_report_generated(). What happens is the followin:

1. if ($premoderated || $hidden) is true so the comment is unpublished
2. afterwards if($hidden && !$premoderated) is true as well so _abuse_disable() is executed
3. _abuse_disable() doesn't do anything because the user has no "direct flag" permission and the threshold is not met

So the comment is unpublished because of 1. but will not be abuse_state is never set. The comment just "vanishes".
