Ross Mayfield is also noticing more spam in his RSS search feeds. By this I mean RSS feeds like PubSub and Technorati's watchlists.

I first noticed this issue back in January. I quickly heard from Bob Wyman of PubSub. Our conversation is posted here. It was encouraging to get such quick feedback from him.

On the Technorati side of the fence, David Sifry quickly commented on a post I made about other RSS spam. If you e-mail technorati at feedback@technorati.com and let them know of any spam blogs, they will investigate and remove them from their index. In the past few months I have probably alerted them to a dozen spam blogs.

It might be a losing battle though, since the problem seems to be getting worse every day.
