the 50 post rule was good and might have actually helped clean up the other forums. This new policy will do nothing and the other forums are already full of spam.
I disagree, I for example don't post a lot but I've been browsing this forum a lot as a guest. Now I want to participate in a specific topic, or gather information about my ideas I am limited to those 5 posts and 4 hours. If I had to post 50 posts, I would end up leaving, since I'm not a spammer...
