The person DukeNuke2 was addressing this to was someone that was advising a poster to "Rule 11: Post questions with descriptive subjects." and to use code tags in the post.
Are we not supposed to help each other get better responses?
If someone posts a thread topic as "Help!" not many people may look at it, and it doesnt help with the web search. Are we (The users) not supposed to HELP them by explaining the rules to them so they get better responses? It sometimes takes hours for mods fix these problems.
Users should allow the Moderators deal with rule infractions. Users can bring a particular post to the attention of the Moderators by using the "Report Post" feature. While we may sometimes miss a post or two, we actually have a very active Moderation Staff.
In the case you cite, a Moderator had already addressed the issue privately. This is not visible to other users. We do not delete nor edit every post that we act on. And sometimes we decide to let a user have a little slack. Our infraction system is largely invisible, but a user who accumulates too infractions is banned.
We have had some cases where Users started quarrelling over the rules and this does not help the site. So please, do report errant posts. But leave the enforcement of the rules to the Moderators.
