Paypal is a trustable company, I am using them for many years and I have not any problem to transferring my money into my bank accounts. Normally I receive always my fund on time in only 2 business days.
So is not a scam site, and they take the security seriously.
People who claim paypal are scam has no evidence about it, otherwise paypal will be charge now. They would not last in the business if they are a scam.
