Crazy question there but please respect my definition of your question you that you ask. Everyone is welcome and if your talking about restrictions well it on your country  that is like China who bans cryptocurrencies and related things to it. So, think about it if its ban on China they might not use this website anymore.

 Plus if americans are restricted here who will know you already created an account if as my definition on banning and if its ban in your country you can't log in as I know and you cant access any accessible machines that is crypto related like, an ATM so you might not get any of your earned money bounties. You can just use it for online selling.
