It isn’t just a server thing. Discord can request a phone number from you if they think something unusual is happening. Trying to create an account while using tor will make them ask for a phone number, and they reject those numbers offered by shared number services.

Last I checked I could only share specific windows, not the whole screen. Later there was also an update with a window or screen selection dialogue that didn’t work at all, I think. After that I stopped using it on wayland.

Linux is the kernel, not the OS. RedStar uses Linux as the kernel.

Yeah I also never reached the end, though I imagine if playing multiplayer, with enough players and time, that then at some point there won’t be any untouched land.
