I've never actively looked around for scammers or even Filipinas that go to internet cafes looking for foreigners, but when I stayed with my Mom in Mindanao, I worked for a photolab. I can't even remember how many guys with boobs caught me by surprise when they asked me to transfer their naughty pictures from their phones to CDs for their foreign boyfriends. Some of them admitted to not telling their boyfriends that they weren't completely female. These people aren't all that easy to catch, especially when you're a foreigner and your eyes aren't trained to see the differences. It's like when I first moved out here to the US, all white guys looked alike. All black guys looked alike. It took a while to be able to distinguish subtle differences in facial features.
