Hi Dien,

The good thing about vbulletin is you don't have to come up with your own hack.

Here is one mod that should stop the spam - and shouldn't take more than a few minutes to set up:

It prevents members from private messaging or adding links / emails to posts before they make x number of posts:

You could also do this to prevent private message spam:

Copy the default "Registered Users" usergroup into another group (say "Fully Registered").

Now set the "Maximum Recipients to Send PMs at a time" permission on the Registered Users group to zero to disable sending PMs.

Add a promotion to upgrade users from Registered to Fully Registered at X number of posts.

You may also want to rename "Registered" to "Newly Registered" or so.

Other mods you may want to look into:
