The term "troll" may also be a slander of opponents in heated debates, a tactic often used by trolls and non-trolls. Many times a person will post a sincere message that they are emotionally sensitive about and trolls know that the easiest way to upset them is to falsely claim that they are a troll. On other occasions a person may not instantly understand or fit into the social norms of a forum where most people are the same - and so acting just slightly out of social norms, often unintentionally, for legitimate reasons gets the poster falsely called a troll. Sometimes when a person just wants to be funny, they are accused of trolling, when that is not their intent. Many trolls now find that the traditional trolling tactics are so overused and commonplace that they have to disguise their trolling to make it effective - although, quite often, the disguising merely involves falsely accusing others of being trolls themselves.
