Spam to cellphones in Japan may not be long for this world. You can now choose to receive mail only from the domains you specify, effectively killing PC-originated spam. Spammers who switch to using cellphones to spam other phones on the same network are rapidly finding themselves cut off. The only really viable option left is to use a cellphone to spam addresses on another carrier's network, but even that's getting harder as carriers become increasingly willing to take offenders to court. The spammers are therefore resorting to a tactic that smacks of desperation: paying random members of the public money to take out phone contracts to give the spammer a "virgin" terminal to work with.
