I think this is a semantic discussion, VirusTotal does return the result of other services, as it is stated in the Website: "VirusTotal simply aggregates the output of different antivirus vendors and URL scanners, it does not produce any verdicts of its own."
Anyway, the point here is: If a site is reported as blacklisted it will be based on something, right? And from what I can see in the aggregated report from VirusTotal all the url scanners show no problem.
