313 has been a mess for decades. Then one of the miscreants started living on 7200 and the 313 dregs followed him there, so he then moved to 7180 and polluted that frequency too. I think it's a nice thing they stick to certain freqs and leave the rest of the ban alone.
I imagine those who despise the fcc would likewise despise these folks if they started jamming pirate radio. They tried to mess with us on 7173 slowscan and one of my comrades said "I'm embarrassed for you" and that was all it took to get them to move along. I fear the day they discover pirate radio, their retardation will be utterly unfettered, however they might need the immediate gratification of their victims howls and thus eschew pirate radio, a decidedly one sided affair.
