Spammer Scum

I’ve just found another load of spam that had been added as random comments to entries on my blog. I’m sure no-one that reads this really thought that I wanted to promote pre-teen porn sites, but it’s still very annoying.

Of course Moveable Type has an IP banning feature and I’ve now banned all of the IP addresses that these comments came from but that’s far too reactive. I’m sure that the next lot will come from a different IP address.

Any suggestions on beating this (short of removing comments from the blog) would be appreciated.
