About a quarter of the communities here have 0 posts in them. We’re going to start pruning the 0-post comms in the next couple of days. If you have a comm with 0 posts that you want to keep alive, please make an on-topic post in it. Otherwise you’re going to lose it.
It’s not an ongoing thing, but every now and then I’m gonna check in and blow away some comms. There isn’t a list per se, but admins can see the full list of comms (it’s actually really annoying because there;s no way to tell whether or not the comm has been removed or not without clicking through into the comm itself – thanks, Lemmy!) and that’s what I’m going to try to use.
