Eliminate…that's a good one.
Well put, Brock. If we make signups any more restrictive, we'll have to require administrative approval before anybody can sign up or post. I don't think that we want to make it that restrictive. So the person who posted that link took the time to register as a human (not a bot), activate their account by responding to a link via an email, and then post a response, just to include a link in it. I also don't think we want to remove the ability for users to enter links in their posts completely. That would be dull.
So, 1 post in ~640 posts so far. Let's keep track of the issue in this thread.
