I'm still not quite clear on the subject of what exactly bold voting is.
however, some kind of filter is required to keep noobs out of voting.
Maybe a 100+ post count or something, or mod approval.
Bold voting was a system where people posted "X Pokemon is Uber/not Uber" (in bold) along with an explanation. In order for your vote to count, your explanation had to be judged as reasonable and intelligent. The biggest problem with it was how hard it was to make judging truly objective - some people would judge an argument as good while others wouldn't, and the fact that not everyone is as good at putting their arguments into words as others hurts too. As far as the potential alternate account problem goes, your account had to be registered beforehand for a certain time period in order for you to vote.
Anyways, we're trying to create the most competitive metagame possible, and to that end, we've created a system that lets the players decide. The definition of Uber is debated a lot, but even when something definite is decided on, the conditions are not something truly mathmatical - overcentralization, what is healthiest for the metagame, etc are all subjective. Letting people who are experienced (deviation requirement) and fairly skilled (rating requirement) at the metagame seems like the best way to do it at this point - it's much better than the other way we've tried, and nothing else that's as good has been suggested. So it may seem like we're banning everything but the kitchen sink, but we're simply aiming for our overall goal, and doing whatever we need to accomplish that.
I feel the need to point out that the bans on Garchomp, Deoxys-S, and Shaymin-S are
NOT permanent - they will be retested during stage 3 of the testing process (or in 1 month in Shaymin's case), so no moves regarding a specific Pokemon or attack have been 100% decided yet. So anything believed to be uber because "it's new so people are afraid of it" will have another chance once the hype has worn off.
Also, the "Shaymin-S Uber voters are crybabies who got butthurt because they were haxed by it" is stupid, largely untrue (reasoning in the voting thread doesn't have to be concrete, so it wouldn't matter if someone posted "Shaymin-S is uber because it looks gay", their vote would still count, and people who did seem to be voting due to one case of hax had better reasoning), and borderline trolling. Don't do it.
