It is...disturbingly easy to catfish guys. Make a Tinder profile that's the "type" of the target (hot, but not unrealistically attractive), set it to show people only within the target's age range (43-43) within 1 mile of their zip code. They'll always be one of the first people to pop up. Just swipe right, and wait.
Since it's passive (as opposed to a clear attempt at making contact) the target never seems to suspect a thing, and they freely give out an insane amount of personal info.
