DTV and online business issue

Hello, I have a quick question.

I have an e-commerce online and I sell worldwide. Sometimes it happens that some thai people buy through my website or social media. Not many, but technically everyone can find my store and place an order.

I know I can’t sell to thai people on DTV, but the thing is that I can’t even block them from doing it...

By the way, my team can ship from Europe to Thailand. It’s not a task that I personally do, but the business is in my name. I don’t sell digital products so we send everything via international couriers. Money always comes on my business bank account.

How can I solve this issue?

Thanks
