Ad nauseam is a Latin phrase... It means, basically, continuing to the point of nausea... That was intended to be a sarcastic remark directed to the "rebranding" of Hotmail over the years as something "new and improved". i.e. hotmail... live.com...outlook.com... Get it? It has nothing to do with advertising "ads"...
The point of the post was the over aggressive spam/junk filter that can't be killed.
