If your foundation is built upon, really teaching people to market for free... and someone comes in misleading them with bad info that will cause them to fail, and charges for it.
Then that person is "Bad".
However if your community's fundamental working principle is to "act like you wanna help people by giving them a little useless free info to lead them into buying something..."
Then a guy who "really wants to help people and give 'em reliable free info, with no catches..." is Bad.
Wait! Why is it that? How could that be bad?
I don't know. Kinda depends on what your community is built upon.
What do you think?
