Sorry I've not rtft, but have reported to fb, and messaged my (ex) local police force with the following:
"I'm not sure if this is the correct way to do this, but I'd like to bring to your attention the following page:
m.facebook.com/pages/Sexy-Little-Girls/668294383191172?id=668294383191172&_rdr
It is sexualising children, but Facebook are refusing to remove it, as they say it contains no nudity. Surely this constitutes a (mild?) form of child pornography?
I now live overseas, otherwise would have called for advice, but am a former officer of (the former) * police, which is why I am a follower of your page and why I decided to pass this information on to yourselves.
Thank you in advance."
Hopefully with all this attention, there has to be some sort of reaction
