I'm not sure if i agree or disagree with the 5 posts. I get why its there but I just think a spammer could do the 5 posts in 1 minute if they wanted. The four hour thing makes sense and sure you really should be reading for at least 4 hours if your a newbie .. although if your an experienced bitcoin trader it might be annoying but hey that's the rules.
Do people automatically get removed from admin after both limits are hit or does the admin check the validity of the 5 posts that are made .. If they enforced a "make the 5 posts good ones" then I totally understand them. One thing for sure is that both limits are set from trial and error so what ever the reason you just gotta respect them.
