I am getting plenty of them. Fortunately there are alway filtered by the rule "more than 2 links", but I wonder why someone would do this (or at least tell some bots to do it)
Looks like comment spam... are you using akismet, or the new service from typepad? I have seen thousands of those back when I actually logged everything.. problem was that the database became huge, as did the logfile if I wrote to a file instead of a database.
