It sometimes happens that users get involved in discussions from which they should stay away, because they are supposed to be private talk. This mostly happens on message walls. However users are allowed to intervene in such discussions if there is a legitimate reason to do so. Nonetheless it shouldn't happen to sabotage discussions. If it seems obvious that users intervene for such a purpose, a block will be issued. As well MoviezWorldwide prohibits starting threads for any obviously dubious purposes such as trolling. Users who engage in that activity can be blocked as well.
