We can't make the general public mods of the entire forum. There's a very specific reason actually. There's secrets that float around these forums :)
I've researched making a mod role that is somewhat limited to not give away those secrets, but the software gives that role no more power to quickly clean up 100s of spam posts then just flagging the posts. It's unfortunate.
The thing you guys have to keep in mind with bots like this is we can't really incorporate new rules into the forum to deal with it. There already are auto-ban and spam prevention rules in place and a lot of spam actually is caught automatically. The problem is that a spam bot doesn't post like a normal user who has to follow the same logic built into the forum software. Some human is signing up, probably making a normal post, capturing the various HTTP events, putting them in some script, hitting execute and then punching a baby or whatever other ridiculous evil things people like this do to pass the time.
I've been reading a lot of suggestions and am bouncing some of them off some of the other admins internally. Last time we were getting spammed a lot I wanted to implement something then as well. Funny enough the issue went away mostly and so I never followed through. That's the funny thing about these spammers, seems like they'll never stop but they eventually do. In the meantime, we'll keep cleaning it up. Trust me, I hate it more then all of you collectively since I feel like I'm on call on my one day off a week. Spam sucks. I'm sorry it exists anywhere.
