> Furthermore YouTube comment are full of spam and YouTube doesn't delete them, so why is it that if they contain certain Chinese keywords (in Chinese) they do delete them?

I think this just shows their spam filtering is not perfect. They delete lots of spam, in both English and Chinese, but some slip through.

Your comment seems to imply that the ONLY comments that are being deleted are the ones with the Chinese keywords. That is certainly not true. It tries to delete all spam, but the spam detection has both false negatives and false positives. That doesn't necessarily mean there is a conspiracy (doesn't mean there isn't, but provides no evidence that there is)

Excuse my bluntness here, but that is a very lazy excuse. A lot of comments are repeated, utter trash that span multiple channels and videos from known bad actors. Sure no spam filtering is perfect but in this case it's obvious YT has gone out of their way to handle that data differently.
