Using Piwik to detect scrapers (no replies)

Yesterday I noticed a site that had been scraping and reproducing my site in its entirety including the piwik calls because it showed up in the live visitor view. You hover over the pages people visited and rather than http://mydomain.com/file.html I was seeing http://scraperdomain.com/file.html Is there a good way to pull this data out of piwik? Show distinct domains that are in the logs for a specific site ID? It'd be helpful to have this as an API call/report I can run regularly to see if anyone else is scraping and displaying my content.

Thanks in advance.
