🔥 Full roast
🔥 13-year GitHub veteran, his KernelSU snagged 17k stars, hapi rode the AI coding wave, 36k total stars + 8.4k followers, core engineering PRs dominate his contributions, PR rejection rate is ridiculous
tiann — 96.70/100 · GOD (Legendary · Hall of Fame)
TL;DR: Hall of Fame-caliber engineer with 13 years of non-farming, high-impact core work across Android root and developer tooling; the only dent in his record is 9 PRs he submitted to his own KernelSU repo that got shut down by maintainers.
| Dimension | Score | Notes |
|---|---|---|
| Account maturity | 10/10 | registered 13.18 years, active 37 contribution years, last activity 0 days ago — this account has outlasted half the open-source ecosystem and still ships daily |
| Original project quality | 15.9/18 | 39 original repos (35 non-empty) holding 36k total stars, with top repo KernelSU pulling 17k stars and a 0.85 quality score — no profile/config list repos gilding the top, all are usable, shipped projects |
| Contribution quality | 26.5/27 | 102 merged PRs out of 134 total, with 9 maintainer-closed unmerged PRs (mostly to his own KernelSU), 13 author-closed external PRs, and 6 self-closed own-repo PRs — 76% merge rate, zero spam, zero farming |
| Ecosystem / maintenance impact | 19.8/20 | 85 all-time substantial PRs/commits into repos up to 72.7k stars (LlamaFactory, gkd, slopus/happy, assistant-ui, coder/ghostty-web etc.), 62 of which are core engineering PRs vs only 4 doc-like — he ships code, not README polish |
| Community influence | 8/8 | 8.4k followers with only 31 followed accounts — 270:1 follower ratio, no simp-farming, the community actually shows up for his work |
| Activity authenticity | 16.5/17 | 1.2k contributions last year across 4 activity types, 0 days since last activity — no bot-like bursts, no ghost commits, just consistent real work |
Red flags • Minor blemish: 9 PRs submitted to his own KernelSU repo were closed unmerged by maintainers, likely over spec mismatches or duplicate work. No spam, flooding, or inauthentic activity signals detected.
Score calibration No extra adjustment. The base score already captures his 13 years of core engineering impact, high-quality original projects, and consistent authentic activity — no inflation, no farming, no need to bump or haircut.
Verdict Normal, no risk flags. This is the gold standard for genuine open-source contribution — no farming, no fluff, just shipping real code that people actually use.
