Blocking new users from adding links and sigs

I remember asking this question quite awhile ago while the newest version 10 was being coded.

It has to do with setting up new user accounts so they cannot post links or signatures until they have a certain number of posts. I spend far too much time deleting/suspending new users that try to use my forum as a form of SEO.

I get tons of spammers on my forum that will register with the intent on posting links and promos in their signatures.

Has this kind of feature been implemented in version 10?
