I was on my noob acc (Reaperoxy) and a runescape gold selling add pops up.....??
By the way:Blurred parts are website urls...

Shows that Jagex don't even pay attention to what they let the F2P'ers view.

I've seen some adverts advertising and cam2cam website for adults :|

I think Jagex needs to stop confusing people about what they let people advertize on their website. I can see some inocent players falling for it. Hopefully you reported that one to Jagex lmao. They might want to remove it asap.
