As long as our "cop" does not make any "thank you" posts, sets protected with values above 1 (ex: [hide=2])should be safe...
This brings another problem: we can see many leechers now that never posted anything. They will only make as many posts as needed to be able to view the contents. Now, that ain't right!!
A really good way to protect this feature would be to create some rule to get everyone more involved, like... 3 months without posting gets suspended account! What do you think?
