So much nonsense going on in this topic.
That right there is a list of countries high to low with at least 25 players from each of them. Of course this is from years ago, but it means Asylum has always been a diverse server. For whatever reason, people from those countries literately chose to play on Asylum - and they've helped in so many ways: increasing server population, making donations, engaging with others, creating fun/funny moments. My best friend lives across the Atlantic and is one of the most authentic and fun guy I've met here.
You all know Asylum's server sits in Canada, right? So region locking it would mean keeping US players out. Sure, make it North American then. What would happen to all the other players from Europe or Latin America? Server will be a goddamn desert during certain times? Okay, reduce the restriction. Would we manually allow other counties as we please? So fucking bigoted.
Now, how about the 'all players should speak English' part? As soon as they join, do we make them upload a certificate? Do we make them go through a listening/speaking/reading English exam? Should they take the damn TOEFL? Another ridiculous idea.
A ping/desync restriction might be a more reasonable suggestion, but that's probably in place already. Like @King has said, if they didn't initiate properly, just report them and move on, they'll have to learn the basics if they wanna keep on playing here. Sounds like the best approach.
