I often hate reporting on threads that do not have any direct link to examples but sometimes you have to trust certain members. A thread at WebmasterWorld has senior member crobb305 claiming that for many searches he is finding "loads of junk and subdomains moving back in" the top results at Google. This is something we have seen with MSN search in the past.
crobb305 continues by explaining;
I sent about 8 "spam" reports in through the Webmaster Tools console. I rarely report stuff, but these urls are junk redirects. One was a blank page!
The thread does have some examples of searches and more discussion backing crobb305's feelings.
Forum discussion at WebmasterWorld.
