I have a woman friend who told me about what some filipinos do, they will join dating sites and sit there with there husbands beside them, whilst they happily chat to foreigners and find ways to scam them, they are even prepared to agree to meet them and have a relationship, so long as they bring some money home.
So my advice and there are genuine people out there, is to tread carefully, and be very very careful. My own experience was to meet someone online then go to the philippines to meet her, and i had an enjoyable time, didnt get robbed or anything like that, but i was looking for a serious relationship, only for her to tell me when i got back to the Uk, that she was already married. No big deal some may say, but had i have known that beforehand i would not have agreed to meet her.
