So, it looks like there are 196 npubs on your mute list that are not encrypted at all, visible to anyone who cares to look. Then there is a chunk of encrypted information in the "content" tag that likely includes other npubs none of us can see, but you alone would be able to see if you go to your mute list in your settings on Amethyst or Coracle. Damus will not show these encrypted entries on your mute list. Most clients don't.
