I would have thought the idea of content filters was to keep minors from seeing inappropriate content? It appears the mobile operator Three have taken the opportunity to sell you "raw xxx videos" when you stumble across a website they think is not appropriate. Now i don't know about you but if I had a kid I would prefer them to view The Best Page In The Universe and not be buying such videos
AFAIK Three have always had an adult section, but you have to verify your age via Credit Card first..... yea right.... "Hey Im looking at porn, here is all my details" lol
