The moderation of other members posts should be handled by moderators, not members.
Moderators have the task to judge whether or not those posts are non-contributory etc or not and whether or not those posts should be removed.
I don't see a lot of duplicate threads, so I don't see it as a big problem.
The only valid solution could be that a member only can delete it's thread if no other members have posts in it.
