Didn't try out the software mentioned in the post myself, but at first glance it seems the guest blogger has ironically created a desktop search tool for warez
Although I suppose it won't be long until a cracked version of CrackTracker appears on those file hosting websites.
Another interesting concept would be to package this in a DLL and include it in the software you want it to protect. When someone runs a cracked copy, it will go see if it can find any relevant links in the browser's history and then auto-report them.
But man.. Reporting browser history to an unrelated software vendor.. Do you by any chance work at SONY?
