how to you prosecute a company that isn't represented in your country ? and how do you get someone, I mean a person, in front of court ?

As far as I know, Nepal can't send its police to America to arrest Facebook CEO and bring him back.

Let's just pretend for a second: Meta deliberately allows pedophiles to organize themselves and abduct Nepalese kids. Nepal government can only publicly object, eventually block Facebook access and that's all ? Nepalese wouldn't be very happy about that.

I am surprised there are even countries where these big corporations don't already have legal representation. It's not like it's expensive compared to what they earn from Nepalese.
