Well, if the fuss is about disclosure then I'm sure we can find quite a few images from this section of people taking pictures of absolute strangers as well. I assume that if we need full disclosure then it's only fair that we disclose those pictures, and the people involved too.
I'm not defending or approving, I'm just stating a simple fact of semantics; we don't really have a total disclosure deal going on this site to say one way or the other. So... it's only fair that if we're going to make this big a deal of it, we should probably point out all other subsequent posts where someone had a picture taken of them.
Also including stolen images from the internet itself, or someone's facebook/instagram.
For the record, I can see and agree with your point here--I'm just also adding it in context that would be fair too, since this is becoming such a heated issue.
