[Reuters]: Popular file-sharing site WinMX.com has shut its doors, along with eDonkey.com, appeared to be closed, following the landmark ruling by the U.S. Supreme Court in June that held anyone who distributes a device used to infringe copyright is liable for the resulting acts of infringement by others. In the wake of the decision, the trade group Recording Industry Association of America (RIAA) last week sent out “cease-and-desist” letters to seven file-sharing groups. A spokeswoman for the RIAA declined to name the targets, but it#039s believe they included including WinMX.com and eDonkey.com. See also Hollywood Reporter.
