Would it be possible to limit the amount of thread topics a poster can submit in a 24 hour period? Perhaps to 2 or 3? It's getting out of hand when the same poster can clog up the main page of the forum and pushing out actual topics that are meant for discussion.

And to further this, would it be possible to auto lock a thread after a certain amount of time? If a topic hasnt been posted in for lets say, 30-45 days, the thread should be moved to auto closed as it is then a dead topic. It makes it worse when not only a poster can post a lot of threads in a short time to clog up the main page, but also go back and necrobump their other threads in an attempt to do the same.
