Its really a shame that some sites have used the term "polyamorous" to mean "open." Now the term has become something other than love, which is what the literal meaning of the word polyamorous is. Otherwise its just sex.
On my okc account I highlighted polyamorous but also added other terms that would indicate I am not interested in cheaters, casual sex or swinging. I make it very clear. As soon as anyone starts talking to me on any other thought I tell them I am not interested and stop acknowledging them. They aren't worth any more of my energy at that point. Really, its always going to be that there are undesirable people to you on dating sites. That is just how it is. Not everyone is compatible to others. So shrugging it off and going in a different direction means not wasting your time.
