Here is the reality. Serious concerns will get few votes. Things such as building a death star that are completely stupid and not serious get lots of votes.
So what this is really saying is, "We're going to raise the threshold so we won't have to waste effort replying to your death star petitions, and btw we don't give a fuck about the little man and never did. Fuck you. Case closed. Now if we can get the media to sponsor some petition we really care about like banning all assault weapons or raising the debt ceiling, then you can vote on that, and we'll be glad to tell you why you have a great idea."
