Chatroulette, the famous random video chat site, is believed to be looking at ways of blocking out penises as the website battles a sharp decline in visitor numbers.

The service designed for the video chat generation was dreamed up late last year by a 17-year-old Russian, Andrey Ternovskiy. It immediately grabbed news headlines around the world for its unique service of random and anonymously linking any computer user in the world to another via their web cam.

While unique visitors to the site jumped five-fold from 18,000 in January to 97,000 users in February, some users have complained that it has been overtaken by a deluge of males who would prefer to put their manhood on display than chat.  Gross.
