As an innocent bystander, and at the risk of getting banned, I have to say I think the post you're replying to was thoughtful and had a substantive point which is that posts that use the comment section to promote their business ventures, especially those that are most likely pyramid schemes, are unwelcome.
You'd rather ban the whistleblower?
I guess you don't like the word "scam" because it assumes a value judgement?

In fact, this very article is about how newspaper websites have turned into advertising spam sites instead of journalism destinations.
The fact that you seem to be advocating advertising in your comment section is worrying to me.
I was attracted to HN because it doesn't feature advertising that I'm aware of (at least not with javascript turned off and an ad-blocking proxy).
If you're trying to let comment-advertisers know you're a safe space for them, I probably won't want to continue visiting.
