Joseph and the BBC's amazing technicolor nightmare vote
Often when these kind of issues occurred with an online vote it would happen because the television or radio production team had consulted with the new media department about their plans too late in the day.
After all, if you are not au fait with the mechanism of the internet, it isn't entirely unreasonable to think that you could easily detect repeat voting. However, unlike telephony, where the user's phone number acts as a unique key, without registration there is no unique key that ties a particular individual to a particular computer when casting a vote.
Which isn't to say that there are not mechanisms for detecting the clumsier attempts to manipulate a votes result.
I remember one vote my BBC team ran about sports personalities. On the very last day of the vote one of them surged from obscurity into the top three. A quick shimmy through the logfiles revealed that all of their new found support had come from one IP block geographically based near the star's hometown.
The golden rule, which I spent a lot of time establishing and discussing with BBC Editorial Policy at the time, was not to use online voting without registration if there was a substantial prize on offer.
In the Joseph musical case the BBC seems to have got caught in a terrible online vote "perfect storm", between a reality TV gameshow audience, pushy showbiz parents, and inter-school rivalry. And local newspapers. And MPs.
There is one fundamental difference between this case and the recent phone scams though.
In the premium line quiz scandals, it has been all of the broadcasters, including the BBC, defrauding and cheating on their audience.
With online voting it is the exact opposite - the audience trying to cheat the broadcaster.
The fall-out in this kind of case still reflects back on the BBC though - the BBC News coverage of the story quotes one person as saying:
My respect for the BBC has plummeted beyond belief!
His faith in the sense of fair play amongst school choirs in the UK seems to have remained unshaken.
I must confess that I am a little surprised, given the recent furore over telephone voting scandals, that the press has not turned their attention to exposing dodgy online votes earlier.
Whilst I'm at it, I would also think that competitions where a winner is picked by a broadcaster at random from a bunch of emails might be fair game for investigation.
And has anyone ever won anything by writing in to one of those promotions that get to claim "no purchase necessary" by saying they'll open a packet for you to see if you win if you simply take the time to send them a note?
