If a user wears a signature in order to earn some mBTC he didn't scam anyone.
There is no proof in him damaging any users at all.
I want to make sure I'm understanding you correctly here. Your argument is that people who promote a scam can't be held accountable as there is no proof their promotion was responsible for users falling victim to said scam?
Keyword is knowingly.
As I said, I would not have worn the signature had I read more about it.
But you can see why I see this as potentially harmful.
Sure, I accept that was a loaded statement on my part, but I think if you are going to promote something and lend your name and reputation to it, then the onus is on you to learn about what you are promoting, and not wait for others to call you out on it.
