Trolling is a deliberate,
bad faith attempt to disrupt the
forum. Ignorance is not trolling. Genuine
dissent is not trolling. Biased
posting, even if defended aggressively, is in itself not trolling. They are only trolling when they are motivated by a program of
malice rather than ignorance or bias. This requires a judgment of the personal motivation for another's action. Such a judgment can never be made with anything approaching certainty. This fact should always be kept in mind when one is tempted to label someone a troll.
When you try to decide if someone is a troll,
strive to assume they are not. Explain errors politely and reasonably; point them towards
the grounds for your contrasting opinions, without personal comments about them. Do not conclude they are a troll until they have shown complete inability or unwillingness to listen to reason or to moderate their position based upon the input of others. Even in that case, it is likely better to remain silent and let others conclude the obvious instead of calling someone a troll and creating even more mayhem. It is better to humor a troll for too long than to drive away a sincere but misguided
forum member.
