This behavior is indicative of a link farm or SEO manipulation tactic, which is often used to distribute malicious content or to improve the ranking of malicious sites. The ClamAV detection of 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a malicious intent, likely related to phishing or traffic redirection.
