I dont think Paypal is a scam, its just that it has a high charges to users. And, many people already used this Paypal globally. Maybe people think its a scam because they find it difficulty to used the service.
YOu're wrong. paypal is the easiest way for the scammer to scam another person through his charge back feature. that's why a lot of people are calling it a scam.
I think that is wrong. Because as long as you can provide a correct proof of transaction to the PayPal then they will not do the reversal of payment. But if you use it against to their terms or which they are not allowing to buy items then you may be in a trouble to get back your money. Since we can't trust people online to send money first so we expect some protection to our money which PayPal is giving to buyers so they are more popular in online payments. If some people are misusing means we can't say Paypal is a scam.
I agree with you. Paypal, on the contrary, tries too hard to fight against scammers. And so sometimes you can freeze any account. It just seems to them that you are doing some kind of machinations. Just need to prove that you are working honestly
