I am, in general, fairly pro-council (despite the fact thus means I'll never get to give input to the metagame) but I feel that seven is a low number. Seven is a bit to prone to bandwagoning, as only two (or even one) people have to jump on the musical carriage for a vote to turn from a simple majority to a super majority, or go down from a simple majority to a minority of voters in favour of banning a suspect. The larger the number of people voting on something, the less of an impact bandwagoning will have on the final outcome. Even a slightly higher number like eleven or thirteen would be the better option, in my opinion.
