The business processes include the phone, texting, and online procedures—how and when to cast votes, and rules limiting the number of votes from each household.
In November 2010, ABC had to defend the legitimacy of its business processes when detractors claimed that Bristol Palin, daughter of political candidate, Sarah Palin, received an inflated vote tally from Tea Party supporters. Some of these supporters bragged on blogs about how they had circumvented the ABC business processes to record multiple votes for Bristol.
