From this question, it appears that the same system for blocking new questions by those that have a history of bad questions used on Stack Overflow also applies to Meta Stack Overflow. Should it?
Downvotes appear to be a significant component of this algorithm (the specifics of which are not released, for obvious reasons). However, downvotes on Meta have a different meaning than those on the mainline sites. On SO, a downvote typically indicates a lazy or poorly structured question.
Here, someone can put significant effort into a proposal and have it downvoted because the crowd disagreed with what was suggested. That doesn't necessarily show laziness or malice, simply someone throwing out an idea that others think won't work.
Therefore, is it appropriate to have the same sort of automated cutoff in place here as on SO? The traffic is much lower here, and this is less of a Google destination for people, thus there are fewer garbage questions. For those that abuse the system, the manual moderation system already in place would seem to work.
