aliexpress had the worst version I had ever seen. I clicked on a link to the French site and got the french version, then I tried to find a way to switch it, saw nothing (couldnt access the footer due to infinite scroll) so I went to the .com version and it was still in french. Cleared my cookies for that site and it was STILL in french for the main page on the .com domain. No idea _what_ they were doing, must have been browser fingerprinting or saving it by IP address. I was not logged in.
