These sites look like they have scraped the results from google and not our actual sites. They then redirect to veryfastsearch PPC Engine when visited.
They are not as it were scraping your site. They are actually giving you a link back – thus a crude attempt at bowling your site. The problem is, the smaller newer sites are going to be hurt by this.
This is technically not illegal and even if we could identify the individual behind these sites, legal action would fail.
As for who is behind it. The person will be using a BP Server or a free hosting site which allows spammy sites. There is also a .pl server that allows free hosting as well. Unfortunately we can only hope google removes them and quickly. I have made a very detailed spam report. I suggest every one else being attacked by these sites also does so.
