Baddog,
Some are not worth adhering to their special rules, as I am sure he would find out.. But I am a big supporter of submitting anywhere and everywhere..
But some Avs allow fpas and some dont, some allow limited banners, limited banner sizes, no hardcore on free area, etc.. and he may find that the fpa's are more valuable than the hits the other Avs sends that doesnt allow fpa and to build seperate tours for the different sites, may not even be woth their traffic..
Again it all depends on your niches and your source of traffic.. everyone's results will vary
I know that when I used to do Avs sites, there were in fact some Avs's that were not worth submitting to..
