That is the sort of thing I am trying to prevent. It is not a freesite list, it is a directory listing domains (websites) not pages.

As far as I can see, your function will not do what I want it to.
I.e. if [url]http://mydomain.com/freesite1/ was in the DB, if they then submitted http://www.mydomain.com/freesite1/, http://web.mydomain.com/freesite1/, http://sub.mydomain.com/freesite1/ and http://another.mydomain.com/freesite1/ it wouldn't catch them.
