Well, the forum doesn't have ethics, people have ethics. Or they don't.
A dealer should reveal himself to be a dealer, or he has no ethics.
And who wants to deal with someone with no ethics...?
About users with hidden agendas
If you know that a user is a dealer and they fail to disclose and attacks other users because they make a point against their interest, do you expose the user?
I know of a gentleman here that continuously posts and goes after people and does not disclose who he is.
What are the ethics of this forum?
