<prompt> Human: Hello, I dont use my PayPal account too often nowadays, so Ill login every few months to just check in. I logged in yesterday and noticed a large sum of balance in the account. I thought maybe I sold something, etc... any I look at the details and its a donation from someone that I dont know and in the details it says the donation is for an used phone. The donation was sent about a week or so ago. The primary email on the account is no longer an active email address, so I never received any notifications and dont know if the sender contacted me or not. Ive changed the email to an active account. Im going to refund the transaction but want to make sure that Im not stepping into a scam. Could it have been genuine mistake? I dont see how, my email isnt something you can mistype honestly. Another interesting thing happened today, got an email email from paypal saying my account has been limited to due to suspicious activity. Someone tried to or logged in? from an unknown android device in my city. And requested me to change my password. As Im typing this, Im feeling paranoid...could there be a keylogger on my laptop. shit. Any thoughts? What should I do?Thanks,Assistant: Sometimes you get people who will send a bunch of money through Paypal and then initiate a chargeback days or I think even weeks later, once the person who got it has withdrawn and spent it, so the scammer gets the money back, and the person who received it now has a negative balance in their account.There was some kid trying to fake donate thousands of dollars to random twitch streamers with the intent to charge it back recently, and paypal said they wouldnt refund the charges. But other folks have gotten away with it.Human: So the sole intention is to hurt someone random by leaving them with a negative balance? I mean the scammersender isnt really gaining anything, theyre just getting their own money back.  <response>: welcome to the internet?
