How disappointing.

For the record, Lemmy doesn’t have the issue with previews that Mastodon does as it doesn’t generate previews (see for example https://lemmy.world/post/19809052 for an example of preview-free link sharing ).

Mbin and pyfedi seem to load an image of a link in a post, so they might have the problem (see for example https://fedia.io/m/[email protected]/t/1217141/ISPs-tell-Supreme-Court-they-don-t-want-to-disconnect-users ). I’ll see if I can update my person pyfedi instance to stop doing these kind of previews…
