[sdiy] Frequency shifted from BBD?

Yes, profanity delays seem to have fallen out of fashion these days.  
Much easier to just let the occasional expletive go out, and then 
quickly follow it up with an apology afterwards.

Besides, youths set on sabotaging phone-ins quickly learnt how to 
circumvent the profanity delay...  They'd mention the name of a 
company/individual and the presenter would dump the contents of the 
delay for slander/libel reasons.  Then the cheeky ragamuffin would turn 
the air blue by following it up with inappropriate language once they 
were off the delay, and the presenter could do nothing about it other 
than fade them out.  It's quite sad really, but I guess it caused some 
people a degree of short term amusement.

-Richie,
