🔥 Full roast
🔥 10k followers, only 33 following, 73k stars all locked in an HTML CS self-learning guide; 22 of your all-time impact PRs are docs-only vs just 13 core code, external PRs are almost entirely docs polis
PKUFlyingPig — 70.00/100 · SOLID (Solid · Trustworthy)
TL;DR: A single 73k-star CS curation guide and 10k followers carry a SOLID score that’s mostly README polishing and course note aggregation, with almost no core engineering footprint outside your own curated garden.
| Dimension | Score | Notes |
|---|---|---|
| Account maturity | 10/10 | Registered 6.4 years, contributions span 7 calendar years with no time-travel anomalies |
| Original project quality | 11/18 | 48 original repos, 84,957 total stars; top repo cs-self-learning scores 0.47 on quality (curation/guide, not usable engineering project), best original repo is MIT6.S081-2020fall (0.9 quality) with 441 stars |
| Contribution quality | 24.9/27 | 72 merged PRs out of 77 total; 2 maintainer-closed unmerged PRs, 3 author-closed external PRs, 0 self-closed own-repo PRs, 3% rejection rate (mostly driven by PRs to your own repos, not external maintainer approval) |
| Ecosystem / maintenance impact | 8/20 | 51 PRs + 278 commits into popular repos all-time; 22 of verified impact PRs are docs/site/examples vs 13 core, so impact is capped at 8 |
| Community influence | 8/8 | 10,029 followers, 33 following — extreme 303:1 asymmetry that reads like a follower filter |
| Activity authenticity | 8.1/17 | 36 contributions last year, 127 days since last activity, 97% of recent PRs locked to your own cs-self-learning repo |
| Red flags |
- Extreme follower/following asymmetry: 10,029 followers vs only 33 following, a 303:1 ratio that’s far outside normal dev behavior and reads like account farming.
- Single-repo dependency: 97% of your recent PRs target your own cs-self-learning repo, a curation/guide project with 73k stars but almost no core engineering substance.
- Docs-heavy impact profile: 22 of your verified all-time popular-repo impact PRs are docs/site/examples/templates work, vs only 13 core engineering PRs, which triggered the impact quality cap.
- Limited recent external contribution: only 15 of your last 50 merged PRs target external repos, with just 1 of those being non-docs work. Score calibration No extra adjustment. The impact quality cap of 8 was correctly applied because your verified impact work is heavily weighted toward docs/curation rather than core engineering, and your low recent external doc-like ratio did not trigger a mandatory non-positive delta. Verdict Normal, but your profile reads more like a curated open-source resume than a record of core engineering contributions — the 73k stars are for a guide, not a shipped tool, and your recent activity is almost entirely polishing your own README instead of contributing to broader projects.
