1 coordinated cluster detected

In production these are held out of every analytic, kept fully readable, and shown with the exact signal that caught them. Removing one permanently takes an administrator and a typed confirmation.

How integrity works

How this works

This runs entirely in your browser, so nothing you paste ever leaves the page. Production screening works on meaning rather than characters, which additionally matches the same complaint across different languages.

Clusters above the threshold are the shape that catches coordinated praise waves: near-identical content arriving from distinct devices inside a short window.
