Remember this?

it flags 3 w's and dot coms and some other stuff so if you wanna post the link you still can but you'll have to bypass the filter

Yeah, but it's a pain to add links and a pain to use them. Maybe @SuperDave might consider allowing links to be posted so long as your account has existed for more than 30 days. It's not a perfect solution but it should stop the porn bots from being able to hoard, while allowing a majority of the real userbase to post links.
