I assume you are talking about banning the topless pictures and not the actual page mumber?
There have been about 65 million petitions over many many years about this, the sun will stop doing it if and when they want to, yet another petition will achieve nothing.
I find it hilarious that out of all the crap in the Sun this is the thing that get people riled up more than anything, its a pair of boobs for goodness sake.
YABU for not putting this in the petitions section though.
