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?

No, if you set the option

{
  pictrs: {
    image_mode: "None"
  }
}

none of the remote media gets stored.

At least the database doesn't have any references to any. And browsing the communities all the images and videos are loaded from external sources.

At the moment I suspect that lemmy is still instructing pict-rs to store them but not actually writing this to the database. But I'd like some proof of that first.
