Utah – maybe it’s not what you would have done, but I don’t know if we should be criticizing the people who did it and speaking badly about them. It could be a LH problem.
In any case, I really don’t think that is what was happening there, and I see no reason to assume such a thing. The most likely possibility is the one that many posters have already given – that they didn’t want people to see untznius pictures.
Even if it weren’t the most likely possibility, but only one possibility, we have a chiyuv to be “dan l’kaf zchus” and assume the best. There is certainly no reason for us to davka assume the worst possible reason
