Best Buy is suing unidentified defendants who are accused of breaking into the computer system of a Best Buy affiliate. The computer hackers allegedly hijacked an email program, and sent spam to people on some of Best Buy's email lists. The spam APPEARED to come from Best Buy, and allegedly contained offensive messages, and links to pornography web sites. The suit was filed in U.S. District Court against John and Jane Doe, and is seeking fines and a court order to prevent the defendants from further use of the Best Buy name. The company's suit is the topic of an article in today's "The Business Journal." Andy Tellijohn is the reporter who wrote the story. He tells MPR's Perry Finelli that there are good reasons to sue against unnamed perpretrators.
