We have standards. We want you to share your authentic thoughts with us and put forth some effort to add value. Sure, it's subjective, but we want to see what we consider to be quality content. We will reward and engage with that type of content and downvote over-rewarded content that doesn't meet our standards. We will call each other out and read each others posts and use our subjective view points to try to get a bigger picture of objective truth.
Maybe we need to make some more clarifying statements, but my little speech there was just what came to mind when I read your post.
RE: So do we have any sort of standards or is proofofbrain a total free for all? also downvotes...
