Tbf, !fediverse@lemmy.ml is there but nowhere else, if you needed updates on Federation software (remember that link will show no posts for you bc you blocked it, but you can click through to see it from another instance including its original one).

And some other communities there are quite large such as Firefox.

Though I still blocked the instance regardless - the trade-off of having to deal with those users just wasn't worth being able to keep those few communities.

Edit: and occasionally I do see good comments from people on that instance, such as the person you responded to - those users aren't universally bad, nor are they the only source of such (lemmy.world is now probably my biggest one these days, surely only bc it's so large and kind-of a default instance). Still, I am enjoying my experience on the Fediverse now that the vast majority of trolling is cut out:-).
