I've never heard about a bank or any other payment or financial institution that can not protect you from scamming.
I was offered to do marketing for those Chinese people and after I finished the job and they liked what I did, they payed me throw paypal.
After 2 weeks the Chinese asked paypal to refund them what they paid me, I refused however paypal froze my money and sent it back to those Chinese.
I was wondering if paypal is a Chinese company?! They protect them however its me who was scammed.
