Hi there, I worked at Match for a while and the basic scam pattern I saw was this: a scammer will create an account and send a ton of messages to recently active users, the users that respond will be immediately prompted to take the conversation to email (away from Match's PM system), and once they're off of Match they ask for more personal information.

I never went further down the path than that but I'm sure the scam could evolve along the lines of "I am your one true love please wire me money to buy a plane ticket to come see you."
