RSS and blogging have attracted their own special kind of spammers - Doc Searls was taken in by one yesterday. I'm seeing a lot of this show up in my BottomFeeder search feeds - IceRocket, Feedster, and PubSub in particular seem to be getting gamed quite a bit.

There was some initial hope that RSS would liberate us from email style spam - it looks like we'll be fighting that battle on new turf - with engines, at least. The good news, of course, is that unsubscribing from a feed - search feed or otherwise - that has turned into a spam bucket is far, far easier than dealing with email spam.
