There are plenty of free dating sites, full of both scammers and genuine people.
After a while (and using your common sense) it easy to sort the wheat from the chaff.
I met my current wonderful girlfriend on a free dating site.
If you're looking for Filipinas try dateinasia.com and 'tagged'.
If they haven't asked you for money after a few messages you may be in luck. 1,000s of potential partners to choose from.
The most likely to be scammers are those who put their occupation as 'student'.
Avoid profiles where the pictures look very professional, and model-like, and do your best to pick out a FEMALE not a ladyboy (unless that's what you're wanting).
Ask them for their Facebook ID. That will be really revealing, and should tell you all you need to know, as long as it hasn't been specially set up for the purpose of scamming.
Also get their email address and type it into google search. That will often bring up their Facebook even without you having already asked for it.
It is very difficult to cover your tracks on the internet these days.
