In mw2 lobby try setting your clantag as IW, it will say infinity ward employees only. Now if you set it as "IW it will let you and then for other people it shows up as IW :)just a little trick one of my friends pointeed out
or you could just get all gamerscore on all of them i dont see why you would need them removed? Pluss you can do this by just going to memmory and deleting it from there...
