Most of the people on here are not worth your time, bro. Aside from fakes, there is then the question of:
proximity: are you close enough to meet with the hotwife or couple to make something happen?
compatibility: do you have matching interests and does your personality and that of the woman or couple gel? and then some.
You'll also find that people get on here and talk a lot of unrealistic or downright stupid talk.
You'll have to be patient and use your common sense and better judgment. That said, there are needles in the haystack here, so be prepared to toss aside a lot of hay, or ignore those for whom there is potential to go absolutely nowhere with. Again, use your ignore button well, and delete messages from the time wasters who may inbox you. They are often from white males, probably with no wife at all but they fake it, or you may get messages from homosexuals trying to get some pics of you naked, etc.
