There is an urgent need to prevent endless requests to view private photos.
Because some users endlessly click on private photos and thus annoy other users.
For example, this can be resolved in such a way that if there is no credit the user cannot request permission to view private photos.
Credits are set by the administrator and the number of credits required to view private photos.
I really think it's necessary, because my experience shows exactly how I wrote that users endlessly click and ask permission to view private photos.
