Yeah, the government's idea is moronic. But making it the victims' responsibility ("don't share your number indiscriminately") is depressing too. How about make it easier to prosecute the unsolicited sending. How about educating people not to be fuckwits..
Yeah prosecution makes lives more difficult, it's rife for abuse (the recipient could fake evidence, the sender could claim he was hacked/his friend took his unlocked phone..)..
