I think with regard to that 90%, what's important to remember is that in our statistics, it was simply a question of whether a photo had been forwarded and not whether it was consensual or not. It was not whether the person reporting it had any issue with it.
There's very little quantitative data worldwide on forwarding. Most if it has focused on consequences rather than simple numbers. One of the issues with having just quantitative data to work with is that we're always looking at research done mostly by other people and other organizations to try to put it into context.
