judgecorp writes "HM Revenue & Customs (HMRC) is extending its campaign against tax cheats with the news that it will use web robots to trawl cyberspace. The system will check eBay and Google to identify traders who aren't declaring all their earnings. From the article: 'The decision to target cyberspace to hunt down those evading tax comes as HMRC continues its campaign to recover around £7 billion lost to the Treasury each year. It is thought that this latest development, the use of ‘web robots’, will help HMRC track down rogue eBay and Gumtree businesses, as well as people earning second incomes by acting as private tutors. It will also help it hunt down so called cash-in-hand handymen and traders.'"
