@RayD_O1 I might be wrong still, but that would kind of make sense to me as to why it kicks non-Europeans out. I'm playing around with the survey now and did notice that there are language options at the beginning between English, French, and German (might not mean much though), but there's a later question about where you're located, and that included non-European countries (maybe if I hadn't closed it to try starting again and selected USA there then it would have kicked me).
Will see what it does if I teleport myself to the USA or something.
Edit: Thought it'd kick me out if I used a VPN but apparently not (tried USA and Oz).
Edit 2: And now I've broken it and it won't let me back in at all haha. You win survey, GG.
