it's funny ralphone, but it seems that you consider that only the mexico photos are not allowed, while there ARE some others that were posted and deleted, on which she was wearing more clothes. so the quantity of clothes she's wearing on the not allowed photos is not a "criteria", or at least not the only one. but you really seem to want to focus on the clothes, good for you.
but as you said, maybe the "criterias" are not "logical" (or don't seem logical to you) but they are hers. full stop. and i don't think someone ever said that there were precise criterias, just that katy requested that some specific pics she detailed to the mods would not appear on the forum. and that's what the mods will try to do.
honestly people, if you really want to know if the photos you want to post are allowed or not, it's quite simple, you have the 2 options : wether you post them and see if they get deleted, wether you ask a mod about the photos before you post them. knowing that in the end, very few photos out of all the paps ones would "match the criterias" of not being posted. just ask the mods about your future photos.
(in an other hand, if you wonder wether you can post the photos you're about to post or not, maybe you have a start of answer there... but the confirmation will come from the mods).
