So I doubt this mass spamming of the FCC will accomplish anything in general. The only thing that talks to the networks is ratings. Regulation gets worked around due to the flexible nature of media.
I don't suppose these folks realize they can change the channel or block material they deem inappropriate via the V-chip stuff built into most TVs and cable boxes these days? Actually, they probably do realize it, but are either hungry for control, or hungry for recognition of their insignificant little opinions on "the way things should be".
