Just to clarify, as it might be helpful for other users, even though the OP decided to leave our community:
The "Your post is queued for approval." message (or any of your native language equivalent) indicates that your submission has to be manually approved by a moderator before it appears to the public audience. It is a measure to combat spam and it only happens for the very first post made by a user. This has nothing to do with reputation system. After your first post has been approved, all your next posts will not be queued, but will appear instantaneously.
Now, if you try to send a couple of post in a row, before moderation has had a chance to review and accept your very first post, the subsequent posts will also be queued. I assume that is what had happened to the OP and that's what made him so angry. The moderators and admins also have to sleep, eat and do other things humans tend to do, so there might be times when the queue is not cleared right away, but rest assured, all posts that are put there are reviewed rather sooner than later. Again, if your queued posts are legitimate and not duplicates of the same post (happens very often) they will all get approved and appear wherever you have posted them. Please have a little patience 🙂
After you reach a certain reputation level, the forums will allow you to post more frequently, as new users have certain restrictions imposed on the amount of time between posts - again, this is to combat spam. That's the only real "benefit" of having a high reputation and most "regular" users probably won't even notice that restriction anyway. So talking about being "in trouble" for having negative reputation is a bit exaggerated, I think.
Finally, I have made some adjustments to forums: from now on to downvote someone's post you have to have a positive reputation yourself, plus all votes are now public so you can see who downvoted you and perhaps try to settle this via PM with that person (if you think it's worth it).
