Juha-Matti Laurio writes "A five-nation tax enforcement cartel has been quietly cracking down on suspected Internet tax cheats, using a sophisticated Web-crawling program to monitor transactions on auction sites and to track operators of online shops, poker, and **** sites. Austria, Denmark, Great Britain, and Canada have joined The Netherlands in pursuing the 'Xenon' program with the assistance of an Amsterdam-based data mining company.

The article notes that the US IRS will neither confirm nor deny using similar technology.
