Mod to Prevent Home Page or Sig Links before X # of posts?

[gregmlb]

Does anyone know of a vB 4.1.X mod that will disallow a user to create a home page link on his member profile and/or a signature link on his member profile before that individual creates X number of posts (where X is adjustable by the admin)?

I tried a search in the Mods section - and all I came up with were mods that disallowed links inside of posts. You can also turn off all home page and signature links in the Admin CP (under User Groups, I think) ... but I don't want to categorically turn them all off.

The reason I ask is that lately (last several weeks), a number of human SPAMMERS have succeeded in registering for my forum, and then they post ridiculous home page links and/or signature links on the User Profile. They don't post anything - but I don't want those links residing in my forum.

Anyone have any ideas? Is there a vB 4.1.X mod that will do what I need?

I'm looking for this as well.
