Not immediately allowing URLs to other web sites

[njkhatri]

I have vB version 3.8.1 installed.

I am always looking for new ways to fight spam on our forums.

And on one of the forums I saw,
>>> You are not allowed to post URLs to other web sites until you have made 15 or more posts.

How do I achieve that?

There is no such feature. The ideal is to stop the spam bots from even registering. You can use one of the human verification options:

Admin CP -> vBulletin Options -> Human Verification Manager (on the left, not the right)

The Q&A option can be very effective. Note that the "image verification" option isn't very effective anymore since some bots are programmed to read those images.

I am already using all that.

I have seen that feature on the vBulletin forum itself. If you like, I can send you the URL in the private message.

They might be using an addon. I recommend you search / ask over on www.vbulletin.org.
