    Project mention: Creators of Tailwind laid off 75% of their engineering team | news.ycombinator.com | 2026-01-07

    I recently had a similar junk PR on my 1,700 star repository: https://github.com/gnat/surreal/pull/56

    I'm fairly convinced these are bot / LLM generated; the content is nonsensical garbage.

    PS: If an LLM needs a whole seperate fork to understand your content, the LLM is failing at it's job.

    PS PS: I want to highlight that the PR itself also seems to be an excuse to get the library quantizor made pulled in as a new dependency. Nasty.
