Something I just noted. I have no clue as to whether this is a feature or a bug but some communities are duplicated across different servers - there are several 'Technology' for example, and I've seen some others - they're clearly not just mirrors or something because the subscriber numbers are wildly different.
As I understand it the Lemmy rules state that you're supposed to check before you create a community, but clearly if you originate it on a different server to the existing one that duplication is allowed. I only mention it because its probably worth keeping an eye out for other 'Freemasonry' communities popping up, so we can let them know that this one already exists...
