Well, you've questioned his parentage in open forum, mis-represented his wargaming and publishing background on a universally read review site, harshly criticized his products on a widely read gaming forum, and issued an all-points consumer bulletin in the online ASL Encyclopedia warning away all comers. I think that pretty much covers all the bases, and any reasonable course of action open to you, given he's done nothing illegal or immoral.
There is, of course, one other option.
That would be to compete directly with him. I'd say if you're really concerned that he's making "too much money" with his poorly designed Vietnam-themed ASL "stuff", the answer would be to design a better product and offer it up at competitive prices. I think that's how America works, or somefink. Then again, when your market includes a small segment of impulse shopping completist hoarders, it probably doesn't matter.
But that being the case, why complain about impulse shopping completist hoarders spending their money any way they want? It's not like they're not buying the good stuff, too.
