In short, it's a cool story, the internet will appreciate it.
Yesterday, one of my good acquaintances was beautifully scammed on Tinder. A girl wrote to him, said everything was fine, and invited him for some "fun." He went to her apartment, and there were 4 guys with knives. They tied him up and said, "Transfer all your money from your card to us yourself, or else..." So he had to transfer everything from his account.
If anything, I'm 100% sure this isn't a joke or a made-up story; I know the guy in real life, I trust him, he's a good guy.
