I asked an LLM if there's ways to detect suspicious starring activity (e.g. if stars were purchased). It suggested checking the project's star history [2] (doesn't appear suspicious).
It also suggested the stars to issues ratio. n8n has 147k:6k (about 25:1) compared to, say, rails with 57k stars and 18k issues (about 3:1).
I haven't looked deeply into n8n (is it 'no-code' for building agents?). I just see hype and am default skeptical.
