“You’ve heard our lead speakers about blog spam and search engine spam and that’s going to get more interesting, but here’s the thing. I put out the call, but I am not getting a lot of papers on search engine spam because, independently, companies think they have a profit in the solution,” Yerazunis said.

“Think of this. If you were Google and you came up with a solution to solve search engine spam, would you publish it? It’s a race among the big three. If Microsoft has solved it, they are going to knock out Google. If Yahoo has it, they are going to knock Microsoft out. The stakes here are billions of dollars,” he said.

There’s tons of cases where private company information’s ended up on a blog and it’s caused trouble. See, for instance, the controversy around Mark Jen at Google in January 2005.
