The thing is on the same day 5 of my sites were deindexed. I did try for an inclusion, but nothing happened. I think it might have been a manual review or a competitor reported my sites. At the time I was using a 3 way link service for the sites so that might have had something to do with it. It could be that one of sites that was linking to me in the 3 way service linked to a bad neighborhood and that transferred to my sites as well. Other than that the only other links for those sites were article directories and blogroll links.
