Recycling cels on homepage

I'm not sure how to explain this. I've been uploading a group of cels over the past week or 10 days, and I keep seeing the same three cels from one gallery reappearing day after day. The cels shift position, e.g., from 1-2-3 to 3-2-1 and so on, but they never disappear.

Today I noticed that these three cels (from Goldorak) were at the bottom of the front page. I then posted a cel, and sure enough, within three minutes of my update, the three cels appeared right above mine as newly posted.

Is there a program that can make this happen, or is this (more likely) exploitation of a loophole in rubberslug? I'm really curious. (And no, I don't plan to try it out!)

I've noticed that, too. I wonder how (and why) they are doing it?

I see that now my cel is properly on page two, posted 22 hours ago, but the cels that used to be just above mine are now toward the top of page 1, and are shown as posted 2 hours ago. So it goes.

i thought the homepage didn't look "fresh" for some reason--now i know why. wild!
