I fell for a sob story about a woman who's kid died and left behind a PS5 they wanted to get rid of. I was kind and sympathetic and said "If you want I can sell it for you and forward you the money" they then asked for money to ship it to me. (I immediately caught the scam there and blocked them). This happened on an open groupme group apparently people can enumerate and join them randomly. in hindsight 1) Don't sell something for someone else-- you dont know if it's stolen and 2) Don't front strangers any credit/money (I didn't)
