Is dating doing good at Fb? is there hard to make that way 500$ daily?
As far as I know, dating is generally banned on FB, unless you get white-listed by a proven/legit dating offer owner ... not sure if anything changed, but that's the way it was last time I checked.
FB traffic obviously convert well with dating offers, so many cloakers run it, but it's not easy to start running in a white hat way.
Dating works very well on FB... especially the casual type... It does require a good cloaker and some creativity, but it's possible for sure 
I'm a dating advertiser and I'm considering working with an affiliate/media buyer who knows cloaking for FB
if you know how to do it or can recommend someone maybe we can set up a direct advertising relationship
