Sorry for my english. Do you think that penguin works the same way for adult sites? for example if i buy some many links on my adult site with exact anchors like "free porn" "sex videos" etc can i get a penguin at all? Is penguin works the same way with all niches or it depends on niche? I mean for example penguin works harder to any sites that sell something and target for "buy something" keyword but penguin works softer with adult related sites? Or penguin is the niche independent algorithm and works the same way with adult, news or movie sites?
