Rules and policies on forums
Forum trolls are users that repeatedly and deliberately breach the netiquette of an established online community, posting inflammatory, extraneous, or off-topic messages to bait or excite users into responding or to test the forum rules and policies, and with that the patience of the forum staff. Their provocative behavior may potentially start flame wars (see below) or other disturbances. Responding to a troll's provocations is commonly known as 'feeding the troll' and is generally discouraged, as it can encourage their disruptive behavior.
Forum spamming is a breach of netiquette where users repeat the same word or phrase over and over, but differs from multiple posting in that spamming is usually a willful act which sometimes has malicious intent. This is a common trolling technique. It can also be traditional spam, unpaid advertisements that are in breach of the forum's rules. Spammers utilize a number of illicit techniques to post their spam, including the use of bonnets.
