It can be because the model release hasn’t been accepted yet by the model. Or if the image got stuck in our upload filter, one of our content moderators need to approve the image in order to get published. This is a way for us to make sure all images are compliant and doesn’t break any rules. We check these many times every day so your image will get published in a few hours.
If the image breaks one of our rules, it will get deleted and in some cases where the images includes something offensive, explicit or inappropriate we take the right to block you. You will be informed of this by one of our moderators.
