I assume people from countries where chips social media account was blocked can still participate? I can access Chips twitter account only with a VPN, and that's not a good idea for most contest that requires you to submit your full details. However, I doubt such strict requirements will be in place for this contest. Another problem is that my government might notice I changed my avatar for a casino, but this is my problem. Hopefully, there will be more contests like art/meme contests that I can participate in in the future.
I don't think there will be any restrictions accessing with vpn if it's not stated there so it is suppose to be an easy access and this shows that anyone can actually participate, do your country have concern with avatar that serious, you will find a way of solving that I love seasons like this because of the fact there a lot of contest so I don't even see the reason why the government will be concerned with something, for sure there will definitely be more contest this something we are certain about. Because you don't even know when you will be lucky to win, a try is not that bad, you might still get lucky at the end of the day.
