That is seriously hilarious that the random characters generated for that video url contained a slur. It has to happen that some really terrible and/or funny things do show up in those random characters on super rare occasion (I think v-sauce talked about this in some episode) but that is some crazy weird luck that it happened to this video about a fake a slur award, subsequently caught by the automod here and that we would find out about it because that filter broke the url when you were trying to show off Hasan's pass for a fake slur.

Alternate shorter video (which almost contains the actual C-word in its URL lmao)

Also, there's a workaround for URLs with filtered words in them—here's a direct link to your video

All I did was percent-encode a as %61. Normally percent encoding is only done for special characters like brackets, parentheses, slashes, and non-ASCII glyphs, but you can percent-encode any character. All you have to do is look up one of the letters in the offending word in an ASCII table and replace the letter with %[hex value].
