PC World - Apple's music-focused social network, Ping is only a few days old, and already the iTunes-based feature is "drowning in scams and spams," security researchers say. The scams are nothing too advanced at the moment, and there are no reports of clickjacking worms or other forms of aggressive malware, experts say. But if you're looking for links to bogus surveys promising free iPhones, iPads, and other assorted iDevices, then Ping in iTunes 10 is the social network for you.
