I have been an active user of different Lemmy.ml communities for a long time but for personal reasons I want to migrate from Dbzer0 to Yiffit, unfortunately to my surprise Lemmy.ml stopped federating with Yiffit a few months ago and honestly it saddens me because there are communities like c/linux, c/privacy, c/firefox, c/fdroid that are extremely useful and I love to participate in them.

Is there any chance that Yiffit will be federated again? And why was it defederated from Lemmy.ml?

The admin of Yiffit is an incredibly nice person and I'm sure he will want to come to collaborate to be able to federate again with Lemmy.ml. As a user I find it a little unfair not to be able to participate in these communities from this instance but I understand and respect that each instance has its own policies and decisions.
