Trackback Spam Overload

People trying to access the Crabitat may have gotten a "suspended" error today. I have just spent a long time on the phone with the hosting company and there appears to be evidence that someone has been trying to hack the site. One URL has been totally banned by the hosting company as a result. That may or may not relieve the problem for now. But I have had to turn the anti-spam image back on as well. That effectively blocks trackbacks. So if you link here, I will try to link back if I see the link, but automatic trackbacks are effectively dead at the moment until we can figure out how to stop this attack.
