Argumentum ad nauseum isn't an argument at all.
An appeal to authority is perfectly valid if the authority is actually an expert in the field under question. In all the arguing around here I have found it exceedingly likely that the folks on my side of the argument are experts and the folks on your side of the argument are unqualified, dishonest and/or biased politically or financially.
