Hiya Basically I was wondering what are the things that set the spam flag in the Google's algo that they decide to manually remove a website. I know a few that are definitely there, like 1 - Over optimized anchor text 2 - Thousands of crappy pages linking to a website I would like to know a few more that you have found to be true. Its quite interesting for me since if you look at something that has gone viral, it will also be linked by thousands of 'crappy' websites. So I guess G would rely on a manual review here (?) thanks.
