I've noticed in my recent adventures into trading seriously again that there has been an influx of traders attempting to scam me with fake paypal invoices. What you'll see in your paypal looks just like the following image. Notice that this invoice says I owe 0 dollars, and that I paid an amount of -65.00. At first glance, this would look like someone refunded me 65$ but that is not the case. If you check your paypal balance it will say whatever it is you started with. When you first open paypal after this invoice is sent, you'll also notice that there is an option to pay your invoice underneath it, even though you owe nothing. This is quite an interesting scam attempt, and something you guys should be made aware of as it's easy to be surprised by if you aren't paying attention. The person who attempted this scam is the person in the steamrep link I shall provide just above the image of the paypal transaction.
