Talk Talk did the same. Auto Nanny filters on so I had to switch them off.
I've axed Talk Talk and gone with Sky. First thing I asked Sky when I was thinking of going with them was could I get onto Airgun and shooting sites and be able to view a pair of t1ts at my own discretion. No one in our house under 22. They said no problem at all. When I then signed up with them and the internet first went live with Sky I had to set their Nanny filters to allow me to view what I wanted. Now I get Emails from Sky telling me that I haven't switched on my Sky Nanny filter which they strongly recommend and suggest I set it to family which will be safe for 13 year olds.
