Trolling / Repeat Trolls
The term troll is a slang term used to describe a number of things, traditionally it refers to a person who posts items intended to incite controversy or conflict. An individual posting honestly-held but controversial opinions is welcome at SDN. However, trolls are not. A troll's primary incentive is the incitement of conflict. Trolls often resort to verbal abuse, making inflammatory remarks maligning the motivation of other guests. Those guests that behave in this manner will be banned immediately and without notice. Banned trolls that return to the SDN Forums will be immediately banned again upon identification of their new account. Those who repeatedly return to troll will have their IP address blocked.
