Keep in mind there are thousands and thousands of customers who do not know of and do not use this site, so you can't base you point on that only a few people have this problem. People who are unfamiliar with technology are afraid of it and more often than not, do not choose to complain about it.
As for consumer speculations, that is the beauty of being a consumer. You have that right.
Bell, as a company, does not have the right to speculate with it's customers. If they don't have hard facts and reasons for why they are calling to bother their customers, then they should not be doing so. It's called harassment.
I suggest you watch what you say because you are partially perceived here as representing Bell even though you state you do not. By having so much "insider" information, it's hard for people to think otherwise.
As for the thousands and thousands of receivers that aren't verified, that is completely Bell's fault and should be rectified by Bell and their lack of a process.
