unfortunately yes, it does happen. We had some friends who hosted a small houseparty. They had been chatting online with a single male and knew he was a single but when he said he had a female friend that would accompany him to parties etc they invited him to their houseparty and after they had been there for awhile discovered that she was in fact a paid prostitute. That didn't go over so well with the other party guests.

We have gotten into the habit of asking couples we meet what the nature of their relationship is and ask if they are married. If they say yes, our next question is, "to each other?" There have been times it turned out they were married but to other people.
