any post that was posted before 2013 was deleted and I was wondering when are you going to fix this issue

The first post on this hub is 2013-07-29. There weren't any posts before that?

The first pic ever uploaded to the hub is still there, so I have no idea what you're talking about. All the blank pages at the end of the index are a glitch.

its possible that the confusion is that the end arrow doesn't go to the end. The end arrow seems to go to page 2615, but the actual end of the gallery is 2622 currently, which you can reach by typing it into the page search.
