We deem spam as making a thread or posting a reply that has no real worth, is irrelevant, useless and offers nothing to a discussion. Spam is not limited to text, posting an image as a means of spam or a spam'esque URL will also result in the same response from a moderator. With spam being hard to define, it is another example of something left to moderator's discretion, if in doubt ask yourself "does my reply add to the discussion in a way for the discussion to continue further"? If not then think of something "meatier" to add to the thread. Repeated spamming will result in any/all of the following:- Post count reduction, warning level increase, temporary restriction from posting.
