Wade your way through the 60% international / out of town spam, then the "platonic only" jokesters, the professional low-end escorts, the send-me-money in advance cheats, the pay $$$ to meet-up swindlers, the I need $5k/month "allowance"...
then you can play the ghosting message game. Finally at the end of the tunnel, you may find one or two gems after 1-3 months of due diligence work.
So if you are willing to do the work, it can pay off. I have found several over the years.
You do have to watch out though, one pulled this "hey I'm pregnant and need $$$$ for an abortion.." con. Good to have the snip-snip first.
