Actually, I'm in favor of much more "telling the users" about these things.
First, as noted by Tim in his comment on an answer in this question, balpha is open to suggestions about how to improve how flags are being (a)bused.
One of the things that I see, that is troubling me, is that the system seems to evolve new features daily, without actually telling most people about them.
Then, when the system suddenly burps, for some apparently random reason, people are clueless as to why it did that.
Take this thing about being suspended for 30 minutes in chat, if chat messages you have are removed because of flags.
The very first thing to do to avoid people wondering about why it happened is to tell those that were suspended exactly the reason. The system does not have to tell them the exact heuristics, nor specifically which posts that caused this, but it needs to tell them that because of people flagging their posts to such a degree that the system removed those messages, they were suspended for 30 minutes. That user can then disagree or not, but if he has an idea about which posts that was flagged, he'll hopefully try to improve.
Secondly, if people are flagging for the wrong reasons, make it clear to those flagging that the people that they are flagging will get suspended if the flags ends up causing the messages to be removed. Even Rebecca suggested that in a comment on balpha's post.
But these are not isolated incidents. The system is gaining new features at an alarming rate, and many of them seem to be aimed at improving the signal-to-noise ratio.
At the very least, then, I would expect those same features to gain sub-features ensuring that the users those features are inflicted upon doesn't cause more noise, when asking why the system did what it did.
In other words, improving signal-to-noise ratio in one part of the system seems to cause noise in another part of the system.
For instance, people have been asking why their answers were automatically moved to a comment. Why not just tell those users when it happens why it was done?
Why do we have to treat users like dogs, hoping they'll react to random shock treatment in the correct way?
End of rant, I suspect this answer will get flagged. At least I won't get suspended for 30 minutes because of it.
