It would be neat to see a black list of all the things Bing and Google block from search results. I don't know how to get such a list other than brute force trial and error.
There's a reason why mainstream search engines like DuckDuckGo perform this kind of blacklisting. Because 99.99% of the time this blacklisting only renders invisible what is worthless anyways. But that 0.01% of the time when it incorrectly blacklists a site HN is outraged.
I can't help but think I've encountered this type of content before...but where.
I also wouldn't exactly call this kind of response "outrage" but something close to befuddled amusement. "Whoops! Looks like we accidentally blocked those sites that criticize us! Yikes." If in err, then what an error! If by intent, then who would believe otherwise?
I suppose some cranky, overly emotional weirdos might get in a tizzy, but this is pretty bog standard stuff. It's just fun to gawk at the sweaty fat man on the tricycle trying to backpedal across the motorway.
