1. Google is trying new algo with new spam filters and new backlinks count. New spam filters could be very unexpected for all of us, but espessialy for the spamy sites.
2. Google is using February indexes now.
3. The best way is to do nothing with the sites . No optimisation, no new links , nothing. Have to wait till the next Google Dance in mid of June. Could be very interesting.
By the way , try “casino” in Google. How do you like the position of the site with the same name ??? Funny, isn’t it ???
