I think most of you know Google and Mozilla are good friend. Recently there are some reports mention Google has penalized Mozilla because of its User Generated Comments (UGC). Matt Cutts now explain the penalty is page specific, since the page got millions of spam comments there. Mozilla shouldn’t allow auto accept comments at the first place, while it’s understandable that Google applies a page specific penalty instead of a sitewide penalty.
So, should we create an account there and spam our competitors, by assuming the penalized page will bring negative impacts to the pointed pages/sites?
