That's the idea, really. Most of the spammers are scripts/bots, and they're written to know their way around the major message board softwares, as I understand it. Just changing the flow should disrupt them a bit, but when Simple Machines (the software for this message board) makes a change, for example, it affects thousands of message boards, so the bots are adapted, and pretty quickly. I figure if I throw in a change unique to this board, it may be able to stop the majority of them. But I've never done it before, so we'll see...
