Surprised there was discussion on this ~2mos after I posted it.
If the link just appears as text, I think this would defeat the spammers purpose. Once the post count for that user reaches 10 let's say, they become hyperlinks. Therefor new members can still post a link, but we have to copy paste (or highlight and right click depending on your browser) only until they reach 10. Or even 5 posts would help over nothing.
Ultimately you are encouraging membership rather than discouraging, but I think anyone actually interested in continual participation will make the effort to reach 10 posts.
Another side of this view is to consider those that WANT to see the forum thrive - ultimately the more ideal member who will continue to add to the forum and provides more content value to Anandtech. If your goal is only to appeal to new members, you may eventually start losing those who really help add the content which lands hits for google searches.
Not that I see anyone leaving over spam (at least at the current rate), it's just something to consider.
Alternatively, let me delete spam when I see it
