The Register: Interview with a link spammer. Well, yesterday I got over 600 phoney trackback entries in my blog. Might very well have been from that guy. Done through proxies from many different IPs, all promoting various gambling sites. Hard to compete with scumback programmers like that.
Hm, for regular comments it works alright to require the entry of some characters from a graphic. There is still spam coming in that way, but it is, I'm sure, done one at a time by manually entering it, so that's not too much of a nuissance. But I can't do that for trackbacks.
I suppose a partial answer would be to spider the site that does the trackback, to see if it really has a link to one's blog. A clever spammer could very well have the link, but he probably doesn't. I'll have to explore that. Another would be to block the sites that are being promoted, but they use so many different changing domains that that's hard to keep up with.
