I agree that it is too harsh you are banned from chat for life. But VS is a private business and they have absolute right to make rules in the way they want.
Here Casinomeister has rules too. It's not like you can say whatever you like here either.
Regarding to Canadian freeroll I believe a few people have pointed out mathematically you guys getting good rewards, comparing 2000 people join netent frerolls to 70 people join Canadian one, and also only Netent freerolls are the ones you can't join, the rest-2/3 of freerolls you guys can play.
If you think closing down is something you want, I respect that, but to be tell you the truth VS is one of the casino that takes care of Canadian people well, I'm pretty sure if it was another casino they would say "You guys can't join the netent freeroll? Tough. We are too busy to create battle for 70 people to join." Not to mention VS is one of a few casinos that allows Canadian to play
Big Time Gaming.
Anyway freeroll weekends is coming. It's Thunderkick game which means you can join, so why don't you have some fun next weekends first before you make any decision?
