This isn’t a “block” as such. You can still view meme and 196 content and 196 from piefed.social. As another user said:
"The code that OP has linked to is part of a convenience function for admins to add content to their new instances. It can query individual remote instances (e.g. lemmy.world), or it can query lemmyverse.net, and fetch communities that look to be popular and active.
It’s completely unrelated to routine federation, and doesn’t prevent anyone subscribing to communities that may have those words in their names."
That nobody is federated to.
That could be the point. No such community on a new instance can be found by others so the original community receives all the attention.
That doesn’t make any sense because it doesn’t block the new 196 community because it uses letters
What do you mean? 196 is part of the list in degenerate_neutron_matter’s comment so a new 196 channel would be blocked.
Do you mean that the official 196 channel uses words and if somebody copies that it is not blocked? True but who would do that?
