Lowest Troll
Who is Lowest Troll? This question can only be settled by frequent trollwar in which one troll ID or troll IP or troll IP range consistently causes the stupidest users to be driven off by trolls retaining the wiser users. This must be without regard for prior relationships or status. The Lowest is the one who resorts LEAST to unequal power relationships and technological escalation, e.g. sysop powers which the LT will never accept and never submit to.
A true Lowest Troll will automatically attempt to ensure that any GodKing or Wikimedia officer is driven off by trolls on general principle, as these people literally invented sysop vandalism and cannot be trusted - they will form power networks that work to the deteriment of all trolls everywhere.
