More WordPress spam fun

For weeks now I’ve been seeing a rather large number of fake trackback attempts from some spam robots. It always uses the user-agent “– WordPress/2.1-alpha3″, and seems to come in waves: one day there will be no accesses, the next, 300–400. The requests span a large number of hosts, around 300 or so. There are also a lot of requests using the user-agent “libghttp/1.0″, but there seems no correlation between the hosts requesting with that agent, and the fake WordPress one.

Anyone else seeing this? Of course, these requests are universally ignored, so no spam is actually leaking out, but it’s still annoying.
