I'm disappointed in RW towers, and their lack of response to this thing. I know that RW has outsourced their web work, so I get that it costs them directly to make changes, and that changes don't necessarily come quickly, but the damage to the forums is beyond ridiculous.
There are technical things that can be done without human intervention. The current wave of spammers are embedding an image in their posts, and all that would be needed would be to programmatically weed out postings with that image/host.
There are also quirks to the html that the spammers kick out that would be easy to find.
Another forum I use has a simple anti-spam button. If 5 people "mark this post as spam" then the post disappears and goes into a moderation queue.
While I've been happy to report spammers in the past, I don't feel like RW is holding up their end of the bargain... for that reason, I'm just gonna abandon ship for a while and hope that they get their house in order. Sigh.
