2. Useless and one-word posts. Do not bother making posts with only one or two words (e.g., "cool" or LOL) or a smilie, or post simply to have the first reply in a thread. Such posts waste everyone's time and will be deleted. Posts saying "I agree", "+1", "this", "me too", or the equivalent are also routinely removed, so don't post them. If you aren't interested in a thread, skip the thread; don't post to tell us you aren't interested. If you celebrate making the first post in a news thread, your post will be deleted.
3. Overposting. Making the same post many times, making multiple pointless posts in the same thread, making numerous posts with no real content, or posting for the purpose of gaining a higher post count.
