I am using Paypal more than 3 years and never got problems, I'm sure Paypall not scam because it already has business units in many cities and countries, even we could withdraw our funds via bank account.
paypal turning out to be scam is utterly impossible, people already know who's the real owner of paypal and its employees, if paypal just start to scam people, it'll be sure only a suicide action for them. Paypal is definitely not scam just their service is kinda succ, it's the worse of the worst
