<prompt> Human: What do I do? How do I know if the money is legit? If it is legit, what are the tax implications? edit: I didnt ask for the money or anything and Im not sure I even know who sent it. I know their username but not who it belongs to.  <response>: Its probably a scam. If the sender requests you send the money back, dont do it yourself. Report it to the bank and have them remove the money. You dont want to end up sending them your own money, then on top of that, they report the transfer as fraudulent and the bank removes an additional 15K.
