Chris Lane discussed Jaded Expats in the Philippines which from my person experience of similar people. Comes down to the fact they are looking for new arrivals and easy prey to bum cash off.
They can generally be found around malls and will have a sob story to suit any expat they come across in the hope they can get a few hundred pesos out of them. Bearing in mind the average wage in Cebu if I remember right was around P6,000 for a Filipino. So if they can scrounge P500 a day off expats they are doing pretty good.
