Google deranked thousands of websites over the night.
 

Hi Guys,
Have you been one of the victims? I cannot believe what happened over the night! Thousands of websites lost their rank on Google including mine!

All people are now bombing Google forums with questions.

Google Groups

Stay away from buying Spam low quality links.

I think it is not just about buying links. There are lots of factors why Google penalized such sites.
