Interesting. I immediately see first two replies as LLM, third sound like a generic pre-LLM bot autopost, the last one sounds kinda legit. Because it’s so short and forward, it’s really hard for me to see LLM behind it. I don’t know what they’re talking about though, maybe it’s easier to spot the bot from semantics POV.
Nothing? In practice, if this were to happen on a noticeable scale it would mean Lemmy has gone mainstream. That said, within a federated system, it’s entirely possible to create isolated, defederated webrings - for example, networks consisting solely of invite-based instances. If something like this becomes a necessity, it might lead to formation of multiple such webrings and they might even decide to federate with each other someday.
