If it quacks like a duck...
I was contacted by a somewhat older gentleman on a poly site, whose profile included this:
I am not trying to change anyones present situation (well maybe a piece of it) but rather to add some REAL excitement to our lives.
I wrote to him and told him that if he was cheating on his wife, he didn't belong on a poly site. He wrote back in a VERY huffy manner, telling me that I was wrong about him and that I had no right to judge anyway.
