The rules are not explained in advance to the users, that would make the system too easy to game, particularly if you were very specific. If the content fails the validation this is the default message that is returned: Correct capitalization and punctuation are required. (ie: All sentences should begin with a capital letter and end with a punctuation mark, etc.) Most people seem to understand and simply clean up their sentence structure a bit. People that have written their entire comment in block caps tend to simply give up.
