It is, or at least partially... From what I understand a user(Lmao/Angled) was "sub-lemmy camping" (took up thousands of popular sub names and wasn't doing anything with them) so lemmy world banned him from that instance. He had a hissy fit and "vowed revenge" and has been attempting to do as much damage to .world as he/they could since. I can't find the original post but https://old.lemmy.world/post/943832 and https://old.lemmy.world/post/1720870 has a bit of detail.
Imagine spending so much time doing something as pointless as that and spending even more time (and maybe money) throwing a hissy fit when things don’t go your way.
If this is accurate it's particularly funny in light of the fact that every instance can have a community of a given name. It's not taken for every instance once one instance makes a community of a particular name, haha.
