Ok, thx for clarifying, but I still have questions
Yourself said that small game devs are not willing to pay anything for their games, and that's true, unless your help is really ground breaking for them (preferably if you can help they earning money as well). If game devs aren't willing to pay, why they would pay you if you just play games? Also, you mentioned your testimonials, but let's be honest, people will always call you an angel if you help them, even more considering you said that you just play games, while they are saying you really boosted their game (I read your whole post btw)
And more, you said that if I don't see value in your stuff, I can just ignore the post, but every game dev sees value on playtesting, except that as I mentioned before, why would I pay you to playtest if there are whole communities for that? And you said for me to comprehend your work, that's why I'm making questions. You can try to convince me your work is better than I think, and then I can consider paying you one day (I need active players for my games, but 10 minutes isn't quite enough), or you can just ignore me if you really consider my questions useless...
