Maybe we could suggest them to make a Membership on their Official Incontinent Cell YouTube Channel. I'm also Asian and I have the same problem as you do. PayPal and Credit Cards are impossible to get your hands on in Thailand (Unless you're very rich and travel a lot).
For Membership on YouTube, there are a lot more Payment Methods for us Asian People that we can easily get our hands on, such as through TrueMoney Wallet and through Google Play (there is even ShopeePay).
