So... what did you do that got you banned?
I know it's popular to hate on PayPal, but they're not in the business of banning people, they're in the business of facilitating payments. Banning people for literally no reason doesn't serve that cause.
Almost every time, when you pull on threads from this sort of story, it unravels into high-risk accounts receiving unusual payments from unusual places all within a limited timeframe where PayPal (or any payments processor for the matter) doesn't have time to evaluate your legitimacy.
Your story might be the one out of a thousand that was on the wrong end of a rouge bot or something, but I have serious doubts.
PayPal processes billions of dollars of payments annually. They don't do that by banning everyone for no reason. Did you use a VPN to deceive them on your location? Did you try to open a business account in the US despite being a UK citizen? Something you did tripped their system into believing you are/were not legitimate, and it's likely you would have also been banned from other similar-tier payment processors, such as CyberSource, Authorize.net, etc.
