Oh, it's only a rogue finger ? That's alright then. At least I find it more convincing than t2w's rogue junior explaination when they had their problems. Though, the bets weren't null and void until people started crying on the interwebs.
There was no evidence there were people facing the other way, or they would be coming here to cry about their lost winnings. I doubt the bucketshop would make a spike without first checking the net effect of the move was in their favour. But, can you not see the danger when the bucketshop chooses to not shadow the real market at selective moments ? Who know which finger is doing what at when ? Isn't it scary they can create spikes with the press of a button ? What other amazing things can they do ?
