If you believe that a post or comment violates the sidebar, then you should report it and message the mods with a link to the reported comment/post and your reasons for why you believe it should be removed. Just reporting something, especially if the reason why it has been reported is not immediately clear, does not help the mods, since all too often users will use the report button as a sort of super-downvote for posts that they simply do not like.

You should also not just comment something along the lines of "I'm going to leave this here for the mods," since we may never see it, and it does not help us do our job at all. Comments, unless they're direct replies to us, will never reach our inbox, and will not solve the problem.
