moderators abusing power, deleting posts and comments just because they can and they think so
sometime you get even persecuted by same moderator
Don't you think that's quite an extreme accusation to make without any evidence or argument whatsoever?
I'm going to go out on a limb and guess that you're talking about this question. Your concerns seem to be wildly off-base here. First of all, the reason for deletion of some comments has been clearly stated:
@albanx, if you'd like to have an open-ended discussion, please feel free to use the chat. This area is for asking questions that can be answered. Please review the guidance in the site tour: mechanics.stackexchange.com/tour. This is not an area for no true scotsman arguments.
In fact, the moderator who left this comment was quite generous. You can't expect comments to be permanent; they're "second-class citizens," and they can be deleted at any time, even without notice.
It is against any rule of democracy and freedom of speech and expression
To quote xkcd, "The right to free speech means the government can't arrest you for what you say. It doesn't mean that anyone else has to listen to your bulls**t, or host you while you share it."
The fact that it is legal for you to post comments here doesn't make it illegal for us to delete them if they are rude, offensive, non-constructive, too chatty, or for any other reason. Stack Exchange sites are community-run: The community as a whole decides what content is appropriate, not just you.
- Only automatic post/comment delete
- Post/comment should be automatically deleted if it has more then 10 negative down-votes (-10)
Automatize as many process as possible
... oh dear. I... don't even know how I can react to this.
Okay, first of all, your question and other valuable meta questions and answers would be deleted just because other people disagree with them. And perfectly valid questions on, say, Stack Overflow, with perfectly valid answers, would also get deleted, just because they're a little low in quality. (Also, comments don't have downvotes.)
But more importantly, almost no stuff that should be deleted would get deleted. Out of the 3701 posts on PPCG, only seventeen of them are voted -10 or below. (Mostly spam or offensive posts, where a spam or offensive/abusive flag gives an extra downvote.) And there are a total of 2319 deleted posts voted +0 or above.
Many positively voted posts get deleted too, for a wide variety of reasons. Votes are not a method of saying "I believe this post should {stay on the site / go away}," and you can't try to make them that.
Make mandatory comment if a post is down-voted
Yeah, this has been discussed to death.
downvotes post
posts comment: "I like coooookies"
It should be in control of all community.
And it is indeed. Moderators are elected directly by the community. You gain privileges as you earn reputation, and a user with the "trusted user" privilege can actually do most of the things that moderators do anyway. Your per-site meta is a perfect place to discuss every aspect of the site, or bring up complaints or requests.
