There is a bit of a title wave effect, I’ll give you that. Comments with positive rating tend to get upvoted, negative ones tend to get downvoted, often for no reason.

Also, people who are red tend to get their stuff upvoted more. That’s not necessarily a good thing in my opinion.

But hiding “bad” comments is also a legit thing to do. Many times they are spammy, off topic, or don’t add anything constructive to the conversation. I think that is much of the reason the system that is here is in place. Things aren’t ‘censored’ in the normal sense that someone out there doesn’t want people to hear the ideas, they are hidden because no one wants to read them.
