My answer to this is to moderate from an instance that doesn't defederate any other instance (other than illegally egregious ones) - SDF.

right, but wouldn't it be best to have an account on the instance the community you moderate is on? Presumably this is the best way to have exact parity - the the community won't support comments or users from instances it defederates from, right?
iirc that's very recommended anyway. Eg. @[email protected] also has the account @[email protected] for moderating [email protected]. Otherwise, many mod actions may not federate correctly to the communitie's instance (or smth)
mod actions generally do federate correctly, at least on the latest lemmy versions. it's just reports that don't.
but in general, you will need an account on the community instance to get full federation abilities when you take potential instance bans and defederations into account. even when it's not a defederation, if a user is banned from your instance but not from the community instance their posts won't make it to you.
You can ban directly using Tesseract and if mod actions federate there it'll ban them, and it'll also remove their comments if you tick remove submissions. I've done it before for users banned from Blahaj but commenting in our communities.
oo, thanks - that's good to know.
Of course! I was just telling you what I do. I didn't claim it was perfect 🙂
oh, sorry - didn't mean that as a critique, just was thinking out loud and wondering if there was a reason I wasn't seeing to moderate from a single open instance (like you) vs the approach of having a moderator account for the instance of the community you moderate 🤔
It depends on where the community is hosted.
If the community is a blahaj based community, then when we defederate, we stop sending community updates to their instance, and we don't accept any updates from people on that instance, so their posts to the community never make it to us.
Which is to say, it is technically possible for folks on the defederated community to post and reply to old stuff in the community that existed before defederation, but even then, it won't reach anyone else. It will just stay on the defederated instance. And they will not get new content, so they aren't secretly replying and interacting to current conversations.
If the community is not based on blahaj, and the instance we have defederated from isn't defederated from the instance that hosts the community, then basically, you need to bring on other mods/alts from the instance that hosts the community.
They can still comment? Wow, Lemmy needs to impliment proper blocking like mastodon has or something. It's terrible that they haven't figured this out yet.
They can't

Yes, that comment showed up after we commented. Still, good to know. It's still a shame that there is no actual genuine user blocking (two way) on lemmy though, so you can see why we thought that maybe they slacked in other areas too.
