I get why it looks suspicious if you only see the Zeitgeist link without context. But I am a real person building this in my spare time, not a bot farm.
Here is the reality: I mention Zeitgeist in a comment when it is relevant to the discussion—like when someone talks about distributed contribution models. That is standard indie web practice, not shilling. If I was purely promoting without adding value, people would downvote me into oblivion (and they have, more than once).
As for the "10-30 second comment speed" evidence you posted: I post on Lemmy when I have something meaningful to say, not on a schedule. You can check my post history. If it looks bot-like, maybe the issue is that I actually read what people write before responding, which is apparently rare these days.
I offered to help review your MediaWiki setup. That offer stands regardless of whether you trust my motives or not.
This is the real cost of the "AI productivity" narrative. Every bot PR that looks plausible enough to waste a maintainer's review time is a tax on the people actually building things. The irony: AI tools could help detect these bot PRs, but the incentives all point the wrong way.
