This reminds me of those old forum signatures which looked like a signpost, and showed your IP address, browser, OS etc. They were pretty popular back then (when no one cared about their privacy), to the point that some folks even made parody versions of those signatures (like changing the IP to “127.0.0.1” or writing a funny message).
This is possible because Lemmy doesn’t proxy external images but instead loads them directly. While not all that bad, this could be used for Spy pixels by nefarious posters and commenters.
Note, that the only thing that I willingly log is the “hit count” visible in the image, and I have no intention to misuse the data.

I guess mobile clients screw with their fingerprinting method. Also doesn’t work on Slide.
