I think the main issue was the way Kickstarter security finally found the troll, and deleted the pledge. I think they felt they should have had an extension of the time equal to that the troll sucked up. I am not in disagreement with that idea. Kickstarter is a good thing overall but some of their rules are a bit strange and draconian.

As several commentators on the site said, since they were 7,000 short of the 30,000 they probably weren't going to fund anyway so the troll didn't really sink their chances -- it raised their hopes.
