Between Friday 23 and Wednesday 28 October the poll associated with Prove It! was manipulated through repeat voting. This was undertaken by those who wanted to be “counted in” and those who wanted to be “counted out” from the statement: "I've seen the evidence. And I want the government to prove they're serious about climate change by negotiating a strong, effective, fair deal at Copenhagen." As a result, to the best of our knowledge, the duplicate votes cast during this period were removed. Internet polls face this risk and the Science Museum has implemented additional security measures to reduce this risk.
5984 individual votes were cast: 764 to counted in and 5220 to counted out. (Correct as at 16.20 Wednesday 28 October)
