Almost guaranteed, especially since HN tends to be popular in tech circles, and also trivial to scrape the entire thing in a couple of hours via the Algolia API.

Recommendation for the future: keep your benchmarks/evaluations private, as otherwise they're basically useless as more models get published that are trained on your data. This is what I do, and usually I don't see the "huge improvements" as other public benchmarks seems to indicate when new models appear.
