I was with Cort till she started in on "public shaming is uncool, taking pictures isn't fair" and then I had to walk away because I know and like her and didn't want to get too pissed off. Public shaming for public bad acts is often the only avenue safely available. And pictures of various people at a con will always be tweeted and blogged, often without their knowledge, unless there's a policy against it. I'm not sure who's served by that handwringing but it surely isn't Adria.
