Delete if false?

I'm trying to make so if the person changes the text inside the script the board will disable its self (to prevent copier's)

if 
	local msg = "Made by NotSoNorm"
	then script.Parent.Parent.Enabled = true
elseif
	local msg = "???" --Help??
	then script.Parent.Parent:Remove()
end

I need it so if it is anything but "Made by NotSoNorm" it will remove the board. Help?

+1 me. -_-

if 
    local msg = "Made by NotSoNorm"
    then script.Parent.Parent.Enabled = true
elseif
    local msg ~= "Made by NotSoNorm" 
    then script.Parent.Parent:Remove()
end
