Third-party ratings and public threads, read directly at the moment of this check. They are easy to buy and easy to brigade, so they are weighted low and can never overturn a lab-evidence flag. Every source below is also logged in the evidence trail.
Trustpilot did not answer, so we treat their reputation there as not visible.

The score is a weighted mean over the pillars we could actually read — 88% of the model on this run. Anything we could not see is left out of the maths rather than counted against the seller.

Reputation is deliberately the lightest pillar. Even a perfect rating cannot lift a report over a lab-evidence flag.
