Ok that I would have to agree is a junk post, and does nothing for the community but tap into the reward pool. So far I personally have not seen any of these posts.
Those posts I would consider to be an abuse of the system. I would hope that the witnesses already know of the major problems and are taking steps to fix them.
But on community guidelines, If a group that is running a supposed bot(s) for the benefit to the steemit community and starts dictating what should and should not be posted. And you refuse to follow them, then this group uses its bot(s) to down vote/flag your post(s). That is when it becomes censorship and not guidelines. I do not believe anyone here can say for sure that it is not happening now.
Yeah, it all depends on how rigidly you believe people "can do anything with their stake that they choose", which is basically what the white paper says...
Thank you for your comments.
