This question already has an answer here:
It seems after you reach a certain number of downvotes (at least on meta), you lose the ability to post. Why?
I also wonder if the algorithm is taking into consideration if the downvotes were spread among several posts or if a single post got many downvotes or if the reason is even considered. If this is a dummy automated algorithm, it needs to be revised.
I also wanted to add that there needs to be a distinction between poor posts and posts (proposed ideas or complaints) which garner a lot of disagreements, hence downvotes. People here tend to downvote something they don't agree with, regardless of the quality of the post. Also some tend to follow the herd. The more a post gets downvotes, the stronger the temptation to downvote it even further by the next visitors.
Also note that meta has a 'discussion' tag. No not every answer or comment here is an answer. This differentiates meta from the rest of the SE sites.
