This site redirects you to other sites. Those sites are picked randomly. Either it sends you in some site where it says that Google selected you to win an Iphone and to put you'r credit cards stuff in, (I checked the scripts, it looks very suspicious as comments always stay the same, and there is no Java Scripts for the comment button, and all the HTML is basic. Google would know how to code better) or it will try to recruit you in some Scammer club. My friend claimed seeing inappropriate content. It might also send you on a site where is claims you have a virus on you'r PC and call that number (to get scammed). Just sad.
