It's probably worth noting that these are livestreams which have chat enabled. You are automatically added as a participant, and show up on the participant list, which anyone can see. I suspect watching, say, the WaPo livestream is fine because they have disabled chat and comments. If you must go to one of these livestreams, for some reason, check to see if chat is enabled, and if so, probably avoid it until Youtube figures out how to deal with this.
