Delete threads if they go into the 10th page.

[HappyZombies]

4chan has 15 threads per page.

They have a total of 10 pages.

15*10 = 150

That means in a given board there are a total of 150 threads.

Create a system that when a thread passes the 10th page (or thread get's to 151 ? how would this work) it will get deleted along with it's comments.
