Did SpiralFrog Try To Fix Hypebot’s Poll Results?

UPDATED: I’ve been running a poll in the right hand column of Hypebot for about a week asking which paid download service has the best chance of success – SprialFrog, We7 or "Other". 
Throughout the week We7 was beating SpiralFrog by about 4 to 1 and as of yesterday evening less than 100 people had voted.

But this morning I awoke to see that 650 726 people had suddenly voted in the survey and that Sprial Frog was now slightly ahead of We7.  Sometime last night Hypebot’s hits started to look like this:
