It seems TOO suspicious that 2 hours before Tsukasa's match with Mikuru and then only a few hours after Kagami's match started (and 1 hour after my quote that 4chan was back) that someone chose the time to hack 4chan and cause it to crash. Think of it this way. If back in Topaz someone had hacked the Vietnam site that was supporting the Negima characters and caused it to crash, resulting in loses for all the Negima characters. If someone from that site asked for a revote, wouldn't you give them the chance? It's just like Sapphire 8 again, only this time people can't get their votes in do to a hacker.
I know animesuki and 4chan may not have the warmest of relationships, but it's an undeniable fact that there are people from 4chan who are/were voting in this tournament (a very good amount actually), and they have every right to vote too and support the characters they want to win. And don't give me that "bookmark" crap. Alot of people don't even know how to use that feature.
