Mobile networks aren’t usually thought of as sources of spam, but a quick look at some of the resources that track spam reveals they actually are.  This is counter intuitive at first glance because when most people think of mobile they think of smartphones, and those aren’t known to be sources of spam (at least not yet).  What’s really going on is PCs connected to mobile networks with air cards, or tethered with a smartphone where it’s permissible, are the culprits.  Bot infected PCs aren’t at all uncommon, and of course bots don’t especially care if they’re using a costly mobile data service to send their spam.
