I hope, this is the right place to ask:
I have the sub !diy_adventure_videos@lemmy.world. Now, in my profile, there are two of them; the former and also !diy_and_adventure_videos@lemmy.world (deleted by creator), which is empty, and I am not even a member, yet I am the moderator.
Might as well be my mistake, but I never noticed it before, so I guess it’s a new thing?
Maybe the empty sub could be purged?
If you’re a mod, you can lock the un-needed /c or restrict posts to mods-only, update the name to say something like (deprecated), add a post with a link to the active /c, etc. to direct anyone who comes across the unneeded /c.
