Spam threads gone wild...

It's 10am EST on a Wednesday  and there are 81 spam threads and about 10 legitimate. I've never seen anything like this online.
I know the Mods. are working on the problem, but at this point, the spammers have taken over the forum and are free to do as they will.

Admin,

This is how to fix the site from SPAM. Monitor each request coming in using a filter. Depending on the web site tech you are using this "filter" will be named differently. Each logged in user will have a username or identity token with the HTTP request. You guys have this saved in you user database. Cross reference this user identity with users who have recently created their login account. Limit these users from posting content based on any rules you guys come up with.

If your developers need someone like me to tell you this. You need new developers.

Thank you, Admin, all gone. But playing catch-up isn't a solution.
