When you open the link, it will show you a fake Youtube Security Validation Screen.
None of the links on that page works
It is a Text area is given to enter the captcha
Submit button says “Add a comment”
when you proceed (it will not check what you entered in the text area) it will show another screen which will say you to complete a survey . By this time it will be posted on your wall, with the text you entered in the validation box as your comment, just because of this the captcha texts showing will be some thing like lol sick, or ha haha or some thing like that.
The page is having a http://whos.amung.us/ link which says there are more than 4000 users online on that page, which shows how severe is that affected.
