Quote from BanzaiBob
Yet both the brands you refer to manage to run contests outside of the US which curse are unable do as it is "impossible"
From your fellow curse employee coldbladed:
"Again, I made every effort to include non-US residents but it is just impossible. Like, Ethan Hunt would not choose to accept this mission"
They only run contests in countries where they have an international headquarters. Being a global country with a HQ in that country allows them to operate under the legal umbrellas of that country.
Curse is a US company so those same foreign(to us) countries impose additional fees and legal hoops to jump through, which is what I was referring to in the rest of that post you quoted.
