YouTube admitted there is an error on “automated enforcement systems” where it’s automatically deleted all the comment that criticized China’s Communist Party. According to YouTube “We’re always working to resolve issues on YouTube” and “We have confirmed this was an error in our enforcement systems”.
All the comments were deleted under video and live streams even if they were used positively. If comments contained the words ”共匪” (“communist bandit”) or ”五毛” (“50-cent party”) then it will detected as comments filters and deleted in around 15 seconds. This issues appears to be accidental.
