Also if say you have image/animation/audio/video link without extension (e.g.: .jpg), you can fool Lemmy using a fragment identifier at the end of URL #.jpg which would usually be used to jump to the fragment id in document. e.g.: https://example.org/image#.jpg

Wowzers that's fancy, I'll have to save that for the future

Now I'm wondering if someone in bad faith could link an tracking image and just rip ip addressees in the background

I guess it depends on if lemmy clients query the link to fetch fetch images or just grab a cached copy of the image from the lemmy instance

Images in comments don't get cached, so absolutely yes. But I mean, public IP + User Agent is like minimum of information anyway. Any website you visit gets it.
