I’m migrating to lemmy.zip, at least for the short term. They also have public instance reports, which was the major reason I joined lemm.ee. Transparency and accountability is essential. I guess the fact that those reports got more and more sparse at lemm.ee was a canary in the coal mine here…

Absolutely. The vast majority of my sites do just fine when whitelisting only the primary domain. I consider it an essential add-on myself.

Lemmy is one of the few that needs a little babysitting, and it’s only for the purpose OP stated.
