So I actually get a lot of Paypal transaction disputes. Someone purchases a product, downloads it, then immediately files an "unauthorized transaction" claim on Paypal. Unfortunately, Paypal pretty much always sides with the buyers because they don't protect digital goods. When this happens, I kill the order from my system as soon as I can. So today I get a PM from one such person, complaining that they are not getting emailed the updates for the product... Seriously? You defraud me and then complain when you don't get support?
