Corrections & changes

The public record.

We grade review sites on whether they own their mistakes, so here are ours: every correction and material change to the grades or the method, with the date and the reason. If you find an error or a stale fact, email corrections@plumbreviews.com — that is the most useful thing you can send us, and the fix lands on this page.

July 11, 2026 Data update

Re-verified the AI models category; entries there now carry July "Last verified" dates. "Site confirmed live" line added to every profile, fed by the monthly automated link monitor, whose raw results are now public at /data/link-health.json.

Why: AI-model leaderboards are the fastest-changing category we grade, and readers could not previously see that liveness is checked at all.

July 11, 2026 Correction

The homepage and report card previously said "Last reviewed July 2026" — the most recent date on the board — while most entries were last verified in June. Both now show the honest range plus the date of the last automated link check.

Why: Quoting only the freshest date overstated how current the board was. That is the kind of spin we grade other sites down for.

July 3, 2026 Correction

Wikileaf and PotGuide outbound links now point to archived snapshots: both domains were sold and redirect to a cannabis retailer, so "Visit" buttons were quietly sending readers to a store. WayofLeaf's link updated to marijuanabreak.com, where its content now lives.

Why: Caught by the July run of the monthly link monitor.

July 3, 2026 Correction

Closed or retired sites (e.g. the Hugging Face Open LLM Leaderboard, AnandTech) now carry a visible "Closed / dormant" chip everywhere and rank below every active site in their category. Previously a retired leaderboard was the #1 result in AI models.

Why: A site that no longer operates must never headline a category a buyer is using today.

July 3, 2026 Correction

Per-entry "Last verified" dates are now shown on every profile, and the site-wide date is computed from the data instead of hand-written (the hand-written one had silently gone stale).

Why: A freshness claim that does not come from the data is a freshness claim that will eventually be false.

June 10, 2026 Method change

Pay-to-rank cap introduced: 44 sites whose own published disclosures say payment can affect ranking order, inclusion, or score are capped at D+ regardless of other scores. Full list and rule at /pay-to-rank.

Why: A ranking whose order can be bought is advertising; the weighted average alone let polish on other dimensions mask that.

June 8, 2026 Data update

Re-check pass on entries flagged by the first link-monitor run; monthly automated link monitoring introduced.

Why: First step of the standing freshness cadence.
