alt Hacker NewsBars probably don't have a directory of everyone that attends the bar, that you scraped and published without permission.
The fact that a person is a student at the school can be very sensitive information. The classic example is someone who leaves an abusive spouse/family and does not want to be found. Now their name and picture is out there, and their timetable and therefore whereabouts could be partially inferred from the school calendar by someone who knows their interests.

But they were already in the directory? That's much more "out there" than the gossip site.
I'm really skeptical of this line of logic. It feels like motivated reasoning based on not liking the site, because a privacy issue like that is easier to attack (if it's real). I think the meaningful criticisms are based on the actual functionality, the commenting.
