This has happened once before and they reversed it. But they said this last time too:
The discussions that have happened in various threads on Lemmy make it very clear that removing the communites before we announced our intent to remove them is not the level of transparency the community expects, and that as stewards of this community we need to be extremely transparent before we do this again in the future as well as make sure that we get feedback around what the planned changes are, because lemmy.world is yours as much as it is ours.
Lemmy makes local copies of everything when federation occurs. It’s 100% on their server. The only exceptions are images posted as part of the comments, those are loaded directly. Then again, that adds the ability to add tracking pixels, so that’s not exactly great for a piracy community either.
Image loading example
I turned off all the logging for this proof of concept but this could’ve been a transparent PNG pixel that tracks every bit of information your browser will give it.
Ayo what the fuck how’d you do that
Your client asks my server for the image, my server does a basic IP location lookup based on a free internet database I downloaded last year and turns it into an image on the fly.
