the best way is to remove the spammer from your database , not to ban , because you lose more time .. then for the GlowHost maybe if you can add a MASS REMOVE USERS

because i have a lot of new accounts created who are robots :-s
Fatal error: Call to a member function query() on a non-object in [path]/forum/includes/functions_ghsom.php on line 386 only i add the option : Remove user , delete all posts and report to StopSpamForum ... (i think is because the users dosen't have any post 100% ) but at least to not showing that error anymore or to write something "the user dosen't have any post " depends of the error .. keep it up , is very good the mod .
thanks
