It's called a post count ban.It's a tradition of MPGH.
You get banned when you get:
1337 posts
2000 posts
3000 posts
4000 posts
5000 posts
6000 posts
7000 posts
etc...
When you post in the General Section try to make your title as nice as possible and don't do [question] shit.
And sometimes Birthday bans too.I will get mine in 22 April I will try to make it exactly at 2k.
