When we post, it should still resemble human behavior, with 1 to 2 minutes intervals it's no longer human behavior, but probably AI.
You are right that it's an abnormal posting behavior, but he isn't using an AI model or a bot to generate and make those posts because an AI would have a more formal writing style. He is writing those posts himself, the purpose behind him doing all this is still unknown though.

I get your point. Even if the posts aren't generated by AI, others might assume that because of how fast they are posted. If you're a genuine member who wants to contribute, there's no need to rush posts, even if they're well thought out. Ideally, you'd read the whole thread to avoid repeating what has already been said, which could lead to spam. Signature campaign managers usually include "no post bursting" in their rules because it doesn't look good. If you're part of a campaign, you should take the time to read, post thoughtfully, and stay on the forum long enough to make proper contributions.
