You raise some good points there abobql. I think I can guess the first two users you mention as I noticed some heavy posting by someone today myself just saying 'thanks' over and over. The other one I think your getting at had the threads closed where he was making a lot of requests.
I'm guessing somebody thought that upping his post count would entitle him to access to the video forums. I'll send a private message explaining it doesn't and we'll keep an eye on the situation.
Thankfully we have a large amount of great members who far outweigh the VERY small number who dont have the forums best interests at heart.
