The content on all the communities seem different.
Why didn’t the “copycats” get the “this community name has already been taken” message?
It was bad enough at The Other Place finding one overlooked sub about one of your interests.
Now you have to find every single community in every single instance if you hope to talk about your topic?
I mean, look at this:
No Stupid Questions@lemmy.world
No Stupid Questions@kbin.social
No Stupid Questions@lemmy.ca
No Stupid Questions@mander.xyz
They don’t get the message that a similar community already exists because they are on separate instances. Due to defederation, it’s possible that not all of those communities will be visible from all other instances. This is one reason why it’s useful to have the same community across multiple instances.
