How to remove single communities from a Lemmy instance as an admin? (ducks.dev)

I have some communities on my small instance that I will never browse, I want to remove them to free up space and not pull useless data (to my one other user and I). I click "Remove" on the community and then I click "Purge" and the community is removed and purged, but a few seconds later the community is back with different content.

I know I can block the communities to stop them from showing up on my "All" feed, but I have a small instance and don't want that data sitting around if nobody will ever look at it, as well as limit the small amount of unnecessary additional strain it may put on other instances. What am I doing wrong?

Is a user on your instance subscribed to that community?

[–] Ducks@ducks.dev 4 points 1 year ago

Nope, previously yes but then unsubscribed and now trying to remove the community

There should be a way to defederate single communitys, it would benefit lemmy.

I am also interested in that

Do you check if it's gone by going to that community's page? Because that'll redownload recent posts from the community. Keep in mind that it won't fetch anything more than that unless a local user subscribes to it.

Nope, I notice it reappear in the community list. If I just remove the community without purge though then the new content stops coming in, so I've just left them as removed without purging

For anyone coming across this, remove seemed to work. Purging clears the "remove" status it looks like and other instances won't know you removed it and keep federating data to you. At least that's what it seems like was happening
