I heard there was a raid and that catalogs got deleted which was kinda worrying but i looked and it doesnt look too bad. here's an idea: give some mods a panic button that stops new replies and threads for 1 hour while popping a sitewide header and emails auto sent to an admin saying the button has been pressed. this way you get receipts of which mod has pressed the button and you can review if it was done appropriately. then, admins can extend the new post preg-vention as needed. This works because this is a slow site and raids/spam rely on momentum and speed. I would say 6 hours for smaller spammers and 24-48 for larger/more sophisticated ones until they fizzle out.
