I would hope that these news and call-in stations are starting to track the numbers that are calling in...I'd be interested if they would provide some generic stats...% of calls with blocked number, % of calls from 416/905/other, % of repeat calls...I think we are all a little suspicious that this is an astroturfing campaign...they could implement a number of procedures to prevent this sort of thing...ie the person calls in, provides a number they can be reached at and are called back immediately...that would stop people with blocked/fake numbers from calling in...
Some of the newspapers (TheStar) could write a story about the procedures and systems in place at some of these call-in shows...my understanding is that some of them show the question to the host before the person is selected (obviously that doesn't stop the person from changing their question) but the honest people with tough questions may never get through...
Clearly they should also identify publicly when any "known numbers" are calling...for example Ian from Etobicoke...I assume he would have been calling from a known number if he had been the mayor...seems pretty straight forward to call this sort of thing out. "It's Ian from Scarborough on the line, who has called this show 5 times in the last month, 3 times as Mayor Ford, once as Gary from Scarborough and once as Ian from Etobicoke...Ian, what's your question?"
