FAQ

What does the cybersecurity sub-ranking cover?

Threat intelligence, breach and vulnerability news, defensive and offensive security tooling, and professional communities all sit here. Channels distributing malware are demoted by the trust check.

Why are trust signals weighted carefully in this niche?

Because security content can itself be a vector for malware or scams, flagged accounts lose ground while credible, verified sources gain a modest edge.
