We all know x-hamster is full of stolen content but so long as they provide a link back, ive never really worried too much about it. Like they have done here
http://xhamster.com/user/cougarchampion
But try clicking on the link back to tacamateurs.com and it comes up with :-
You are leaving xHamster.com and visiting another site: http://www.tacamateurs.com/cougarchampion/. Please, notice that some sites may contains malicious things such as viruses, adware, spyware etc. So, if you are really sure - click to proceed. If not, you can return to the previous page.
That is just blatantly trying to stop users visiting contributors sites !
