do you think people who are married or in relationships should be signing up on date sites?

I think they need to mention they are married and are enormous scumbag cheaters right in their ad. I remember going on ONE date with an older guy who tried very hard to get me drunk, and then wanted to go to a motel...sure sign he is married, (can't take you home). THEN he told me he is always free on Thursday nights. That's another clue...only free one night means his wife is out with the girls playing bridge that night.
