The reason might be that users often pick fights with mods. Dan’s comment page might be overwhelmed by such threads if left unchecked. pg once noted that pg’s own account was highly watched relative to other accounts, so maybe users were following Dan around and adding fuel to the very fires he was trying to put out.
The reason I say that is because I can’t find any examples of this phenomenon except his account. Do you know of any? E.g. this thread does show up on the flagged user’s profile page, contrary to what others were saying. It’s right below this one for me: https://news.ycombinator.com/threads?id=breck&next=34266186#...
It also seems to show up on everyone else’s page: mine, tptacek’s, etc.
Cheers for pointing that out. Stuff like this is fascinating, and we rarely get the chance to nerd out about it.
EDIT: interestingly, https://news.ycombinator.com/item?id=34265016 does show up.
