Why is my pict-rs writing data? (swg-empire.de)

In my quest to tame my pict-rs instance I've disabled thumbnail proxying, deleted all thumbnails and images not uploaded by me and still the files folder is several GB big. And growing.

I am the only user of my instance. But iotop shows constant disc activity for pict-rs. It's writing stuff at about 1 MB/s. The webserver logs only show my own activity and occasionally someone requesting an image. But not nearly enough to explain this constant activity.

When I'm looking at the actual files at random it seems to be mostly memes and stuff, but not what I uploaded myself.

Does anyone have an idea how I can find out what is causing all this activity?

I looked at the files modified in the last hour and it's only three old pictures uploaded by me a few weeks ago. I compared one of them and it's actually larger than the original.

original

pictrs

I'll try to find the related post to compare.

Edit: the image from the post is different from the other two. A few bytes smaller than the original.

This is all very strange.
