FCC tries its hand regulating SPAM on phones
Written on the original Movable Type site and recovered from the Internet Archive.
The FCC has tried a new rule to combat mobile spam. I would guess that they have more leverage over that (relatively) closed network than the internet in general. In mobile, there are fewer entry points into the network and therefor more control. There are always ways in and around though. And I also see that legitimate players like SOHU can still run afoul of the laws.
