Hey, thanks for the extra insight, I do appreciate. Interesting to know that those sites show these behaviours too. Why could geo-location based redirect be interesting?
My guess would be that maybe sites have different infrastructure in different regions and maybe they aren't completely aligned on their progress. I really don't know why you'd intentionally have it like that.
I thought about country restrictions as well. I noticed most of the offending websites were in China. Wondering is having SSL there is not allowed or something.
