I think that it's important that we have a free market here.
If freedom is the key factor, and he's free to sell his crap, we're free to comment on that, right?
His self-moderated thread doesn't allow that, as all comments that could make his product look bad are removed (it's even closed now, sales continue "in private").
This thread allows us to, and is the right action according to the forum rules. Despite some peoples impression, this thread is not to restrict freedom, it's to ensure it.
I posted on his thread asking a genuine question and then he sent me a PM accusing me of trolling.
I pointed out their mistake about Anonymous/FSociety and got deleted right away. It's their way to act with others.
I understand your point of vue, unfortunately I think as cryptocurrencies will become more and more famous in the future, there will be more and more people who will try to create and sell physical crypto, and there will always be people for buying crap...
We should continue to try calling out stuff like that.
