I used to do this back in the day to augment my Netflix selection.
All the geo-IP nonsense is absolutely crazy, including these random login blocks and "security" checks. You also get UI reset to languages you don't understand, because no, websites can't use the language you set in your browser, they have to use some geo-IP nonsense to select a language (especially funny with IPv6). And there's no persistent switch if you use private mode, because they don't respect UA settings.
