The fact that you have some photos that are not visible or flagged is due to a new system that has been installed that automatically blocks any photographs it believes to have unsuitable content.
In the event that some of your flagged photos do comply with our standards but are blocked, do not worry, the system might recognize photos as inappropriate because of lighting, color, the composition or even the quality (Mpx) of the photos.
All photos that have been blocked are manually reviewed and the ones that are not against our policy are returned to the user’s profile. This revision is made as soon as possible in order to put them back where they belong.
As a reminder, Agora's basic norms to upload photos are:
“All photos are permitted with the exception of images which infringe human rights, contain pornography or defamation, or which foster hatred, mistreatment, discrimination, violent behavior, racism and/or xenophobia. Images must be apt for any audience, and not be in contention with the law and/or public order.”
