Hello. We have an older Ning instance on grasshopper3d.com. One of our admins banned a user for spam, and after some discussion with the user to correct the behavior, we reinstated the user's status. After this, some of the user's images are missing. For example, here is a link to a missing image: https://api.ning.com/files/t5Y0oOviE8I3XardZNu5nb6ZyQaFb-7ukZSoT7y3qzRv5fOxHNJ6eQr72jH8DVJFAdmuLDKWfbSm*4BpmmRzewEe6go201CF/IMG_0864.JPG
It gives a 404 error not found:
The strange thing is that not all of the images have gone, and the ones that do go missing do so gradually. Just last night, more images went missing. On this user's gallery, there are entries for the images, including the title, image description, general metadata, just the actual image file cannot be found.
How can we track down the source of this issue? Are the images gone? Why would they be progressively erased? This has not happened with any other user, and it is very rare that we reinstate a banned user, thus, it is the only time we see such activity.
