I found a hack from amykhar on Vbulletin.org and it helps a great deal to fight spam and link dumping on forums.
This hack will not allow new members to post any URL in their posts and advertise till the time they reach 5 minimum posts.
And if they make 5 posts and still spam, i will ban their account.
I have already noticed not even a single spam message since i installed the hack.
Management will be much easier now
