Earlier quoted context omitted.
The problem is publicly posting a creepily-taken photograph of two friends at a conference, with entirely baseless slanderous claims of something you allegedly overheard them say to each other.
Baseless? PyCon disagrees, and apparently, so do the two friends. http://pycon.blogspot.com/2013/03/pycon-response-to-inapprop... So, unless PyCon is lying, the claims were verified. If they had not been, you'd have a point. If she had made the claims, but never went to PyCon and resolved it properly, you'd be dead on.
My point is that at the time she decided to take this photo (seemingly just after she overheard the statement) the claims were unverified. Had they not been able to verify the claims then it would have been too late.
