After some advertisers on the radio station got threats, the person responsible decided to pull the ad, which he said was his creation and no one paid for it.

This is something that could use some investigating:

PHOENIX (AP) — An oldies country music radio station serving a rural Arizona area that aired a public service announcement for two years telling people how to hide potential evidence in child pornography cases has stopped doing so after advertisers received threats, the station's owner said Wednesday.

KAVV-FM owner Paul Lotsof said in an interview that he does not like child pornography but created the announcement because he thinks Arizona's 10-year minimum sentence for each image of child porn is too harsh and costly for taxpayers.

(The announcement) said: "If you have such material, you can save yourselves and your family a ton of grief and save the taxpayers a lot of money by never storing such pictures on the hard drive of your computer. Always use an external drive and hide it where nobody will ever find it. Likewise, never keep paper pictures, tapes or films of naked juveniles where anybody else can find them."
