And he also sells their products, and they sell his. There is some kind of partnership there. Mi respect the confidentiality of any agreement between him and ProVape, but there is no denying there is a relationship there.Zen has a very wry sense of humor that can be taken wrong. He also has a huge amount of knowledge on these subjects and has done a lot of research/testing so you can pretty much take what he says as fact and if he doesn't know all the facts he will say so.
You will also notice he has refused to disrespect provape by touting his own competing PV. That alone speaks volumes about his integrity.
As for the mods, they take a looser approach to supplier forums and let the supplier decide what is allowed unless it goes against forum rules or are asked to step in. Robino1 can explain it better though.
As the fact that there is a business relationship there, I don't take everything he says as fact. Do I doubt he has experience? No. Do I think he knows nothing? No, I do believe the man has experience, and is fairly knowledgeable...but I can't overlook the fact that some things are coming across with bias. As a machinist, I have nothing but respect for the man, his creations are works of art. I also respect that he has his opinions on what a good Vape is, and what isn't. Just like some f us Vape tobacco flavors, some others Vape candy flavors and so on. I also respect his right to voice his opinion.... Where I find fault is his way of voicing opinion is done as an attack on others, or as "fact".
