The long story short many Thai people lost their money due to variuos policy's of PayPal , on top businesses loose money on charge back by fraudster . So many complaints made to Singapore Government ( As they were registered ) so now they are not allowed to do business with individual only business with strict paperwork. But if you have registered PayPal account outside thailand you can use it .
