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.
