I openly state on my POF profile that I'm happily married and have a boyfriend. One guy messaged me and said, "So are you insatiable, or just greedy?" I told him I am neither, I'm poly. He countered back with, "If that's what you want to call it."
He left me alone after I commented that he must have a winning strategy for picking up women, if he has nothing better to do than troll a slut's profile.
