The stars and the platforms we read

A listing's stars are the average of its ratings on the platforms on the right, weighted by how many reviews each platform holds, plus the reviews published on smm.guide.

4.7
83 reviews on 5 platforms · prm4u.com
  • Weighted by volume. Forty-nine reviews on Slashdot weigh more than four on RealReviews; a 5.0 from two people cannot outrank a 4.6 from two hundred.
  • Named sources only. Forum threads, blog write-ups, catalog listings and automated "trust scanners" carry no weight.
  • Read from the live page. A figure we could not confirm on the platform itself is ignored.
  • Nothing imported, nothing seeded. A number without a source is not a rating. The platforms behind every card are printed on it.

A platform where a panel is absent counts neither for nor against it. A verified owner adds the address of the panel's page on any platform we have not found from the dashboard, section Listing & SEO — we open the page, make sure it is about that panel, read the rating and put it on the card within the hour.

The Trust Score, 0 to 100

Three groups. Longevity is measured, openness is in the owner's hands, reputation has to be earned — and can be lost.

Unknown age is scored as one year. A record that claims five years while the archive first saw the site less than eighteen months ago is scored by the archive.

Stars translate to points on this scale, per bucket, at full review weight. Bad reviews cost points; silence earns none.

What the number means

Above 75 is reachable only with an open panel and real reviews. Unknown earns nothing; bad reviews cost points.

Order in the catalog

Verified owners rank above unclaimed listings, and TrustPanel listings rank above Verified ones. Inside each group the Trust Score decides; among unclaimed panels the stars decide first, then the score — and a single 5-star review is pulled toward the catalog average, so it cannot outrank a 4.3 from forty reviews.
