Unwanted redirect to landing pages of parked domains.
A typical scenario is when a website uses a third-party script whose domain got expired and later purchased by someone who parked that domain name. The service that provided parking hijacks requests to JavaScript files and replaces them with a redirect command.
Or it may be a sign that some took the domain you scan over and it no longer points to a real site.
Affecting: Any web site (no specific target).
