🔥 Full roast
🔥 15-year OSS veteran, de facto captain of top browser-extension projects Violentmonkey and Stylus, with 163 popular-repo PRs and 3,724 commits backing a 96.6 score, plus a 0-following list that screams
tophf — 96.60/100 · GOD (Legendary · Hall of Fame)
TL;DR: Legitimate Hall of Fame-tier maintainer of two top browser extensions, with 15 years of non-stop, high-impact contributions; the only thing he can't seem to ship is a single follow, leaving his following list as empty as a repo with no commits.
| Dimension | Score | Notes |
|---|---|---|
| Account maturity | 10/10 | Registered 14.48 years ago, with contributions spanning 15 full calendar years — nearly the entire life of the account, with no meaningful gaps. |
| Original project quality | 18/18 | 17 non-empty original repos, 15,601 total stars, top repo violentmonkey/violentmonkey (8,430 stars) is a fully attributed org-led flagship project with a perfect quality score, no empty repos or star inflation. |
| Contribution quality | 26.9/27 | 578 merged PRs out of 639 total, only 9 maintainer-closed unmerged PRs (2% rejection rate), 50 author-closed external PRs, 0 self-closed own-repo PRs, trivial PR ratio sits at a low 3% — consistent, accepted work, not spam. |
| Ecosystem / maintenance impact | 19/20 | 163 PRs + 3,724 commits into popular repos (all-time total; verified file samples are a small slice for quality review, not the full count) across 5 high-star repos including codemirror/codemirror5 (27k stars) and jantimon/html-webpack-plugin (10k stars), plus 1,570 commits alone in Violentmonkey. |
| Community influence | 6.4/8 | 184 followers, follows 0 users — high impact built entirely on shipped code, zero follower farming or social grooming. |
| Activity authenticity | 16.3/17 | 1,047 contributions in the last year, active across 4 activity types, last activity 56 days ago — no bot behavior, no long gaps, consistent real work. |
Red flags
- Recent merged-PR sample is 80% concentrated on violentmonkey, creating single-project dependency risk; all-time data confirms broader multi-repo contributions, but the recent snapshot is heavily skewed to one flagship project.
- Follows 0 users, an unusual quirk for a high-impact maintainer that reads less like anti-social and more like "I have better things to do than collect follows."
- The account's public value is tightly bound to attributed org maintainer roles for violentmonkey and openstyles/stylus; losing access to those orgs would wipe out most of the visible contribution surface overnight.
Score calibration No extra adjustment. The base score already accounts for the 15-year sustained activity, attributed flagship org projects, 3,724 all-time popular-repo commits, 2% PR rejection rate, and lack of any suspicious behavior like PR flooding, templated spam, or star inflation.
Verdict Normal, high-trust maintainer. This is a legitimate, high-impact open-source contributor whose 96.6 score reflects real, sustained engineering work on widely used browser extensions, with no red flags that would warrant a score adjustment or manual review escalation.
