when i was 12/13 i met a guy on Habbo who became my first e-boyfriend, turns out he was using photos of him from like 5 years ago and he had gained a TON of weight since. he was really good at covering it up, but i caught him out when i stalked his mother's facebook profile and there was a photo of a car with him tagged in the window which was reflecting some fat bearded guy's face .. so i sent it to him like "girl .. tell me the truth" and he came clean
also sometimes when a guy on grindr is mean to me i'll make a new profile w/ my hot friend's pics and get them to walk or drive for miles to hook up and then just stand them up .. sometimes i even ride by on my bicycle as they're waiting and laugh to myself
