I've noticed a lot of spam recently and it seems that the admins need to manually go to every thread and delete them, so I'm thinking perhaps an idea would be to add a "Report User" link to each post and any posts reported are automatically linked to in a queue/admin-only board. This will make it easier for users to report spammers (and other abusive users) and for the admins to delete them. Once a post is reported the "Report User" link can be disabled for that post so as to avoid duplicate links in the queue.
