Bad idea to remove it completely. I go though a lot of posts everyday and you would be surprised at what goes on with high frequency posting. One big vote on some garbage post and there is an immediate flood of those kind of posts from scammers trying to make a quick buck. If they are going to remove it it should be reputation based. Increase it to say 5 a day at rep 50, 6 a day at 60 and remove at somewhere between 62 and 65.
