i think the probowl is a joke, but still i have to wonder...are any of you guys voting using imacro?
it's pretty easy to record your action of voting and set it to repeat hundreds and thousands of times, tho i would recommend doing just one player at a time.
if you have firefox or chrome, just download the free version of iMacro
go to pro bowl voting site
in iMacros window, click record
vote for the player you want
click submit ballot
click vote again.
stop the macro
then click to play the macro and put in the max number of repeats you want (thousands if you want) and hit 'play (loop)'.
