Tell your instance admin to restart the Lemmy service every so often. We have ours restart every six hours since that fixes the hot thing breaking and getting stale.

Larger instances might not be able to restart often as it could leave some interactions in limbo.

I’d say people worrying about Karma.

I’d be more inclined to reach out to Louis Rossmann, especially since he’s said he won’t post on reddit anymore. Maybe we can even find a home on lemmy for his right to repair campaign.

There’s currently no way to do this. It’s a planned feature though.
