Avoid using more than one exclamation point or question mark at the end of sentences, like

Don't sign your posts with your social security number and mother's maiden name, like

Don't pepper your posts with racial slurs.
Don't include pornographic images in any screen captures you include in your posts.
Et cetera, et cetera....
My point is that some expectations are common sense and (nearly) universal, and it's a fool's errand to start including these sorts of "pointers" on the help page.
Sure, maybe an automatic check for all caps could be useful, but my feeling is that this is a relatively rare problem that is already effectively addressed by the site's community review processes. It's probably not worth the effort to implement. Sorry.
