I live in China and this software is cancerous not just in the encryption failure, it also nestles into a computer like a trojan. Creates 2 fallback installations and will reinstall itself after removal if you reboot in between, unless you get rid of all 3 installations at once, where they are deliberately trying to obfuscate the uninstall button (triple confirmation, swapping the confirm/cancel buttons and button background colors, etc.).
It's a nasty piece of crap that come preloaded on any phone (android, at least) and Windows-PC here.
Filter is not block though, if you open the instance on your browser, you still see them. Only if you actually block them, they are gone.
