Trolls nest
A trolls nest is where trolls plan responses to sysop vandalism, and other forms of troll vandalism.
It is expected to become a major issue for the Consumerium Governance Organization, as it has already for Wikimedia. Prominent nests are rare as they are usually secretive.
Most trolls' nests are not so visible or overt in what they do, and exist as private webs and intranet services. For instance transnational corporations employ funded trolls or "spin doctors" to spout propaganda into the large public wikis to counter trollish truth-telling.
