Well, I don't use the forum to sell the diffuser. Even people that happen to pm me, I move the conversation to other forms of communication. I don't see any thin line, I very intentionally follow the rules of the forum. I also post photos here and help people copy my stuff if they want to build their own, but I guess I could not participate in the forum at all. I'm in the army, the diffusers aren't a paycheck. I'm not a parts vendor.
What about other people who build parts but aren't vendors on here, like Stillen or fab guy?
Maybe he could've posted this under a product review instead of a vendor review. So we have that type of sub forum?
