The author of these images has admitted they are fake: http://www.wow.com/2010/07/08/that-scary...fake-guys/
In addition I have disabled photo uploads on the forums due to excessive posting of offensive imagery.
There is also a video of it here: http://www.youtube.com/watch?v=-PQtNRKZq04
The effect in the video can be achieved with a very very simple addon that would look like:
function SomeFunctionName(arg1, arg2)
local realid = "Some Fake Name";
GameTooltip:AddLine("|cff00ffffRealID: |r"..realid, 1,1,1);
end
GameTooltip:HookScript("OnTooltipSetUnit", SomeFunctionName);
local realid = "Some Fake Name";
GameTooltip:AddLine(
end
GameTooltip:Hook
The 2nd line sets a variable as to what fake name you want to use, simply create an array of fake names and you can choose them at random or make them show for specific char names to make the effect look more convincing.
