I don't see anyone here saying that using AdNauseam is ad fraud (unless you're visiting your own site with it). What the other comments you seem to be referring to are saying is that AdNauseam's behavior is similar to ad fraud, and therefore detectable via the same mechanisms that detect ad fraud. The term itself is perfectly reasonable. If you're intentionally clicking ads on your own site in order to mislead the advertising provider about your CTR and thus generate more revenue for yourself, that's clearly fraud.
