I looked through some topics were accounts created in Scratch 2.0 can set their location as “Location not given” (I think?)

Is it still possible to do this? I know the inspect version of it was patched but is there some other way to do this?

No, unless you are part of a class and your teacher set your location to that. I'm not sure if that also works though.

Yeah - it used to be the default setting when you set location. I've still got it on my profile, but I don't recall an inspect way of doing it?
