The 10 posts rule has always made me chuckle. I dont spend time on many other forums...a couple other cycling forums from time to time and a college sports forum is all.
None have this delayed use requirement.
If something is spam, then shut it down. If someone is misusing the forums, then shut em down.
It's quite simple. The 10 posts requirement doesnt keep spammers and trolls away, so why have it?
But I dont know how the sausage is made. Perhaps the mods are keeping 95% of spammers and socks away due to their newbies policies.
