As author has since removed links, this should address your concern. Being wary of Amazon links is probably smart, but referring to something as "garbage" just makes you a jerk.
You need to stop slinging accusations at people. Gaming HN is bad. We greatly appreciate your and other users' concern about that, and believe me we share it. But undermining civility on HN is also bad, and that's the bad thing that actually is happening here. Please don't do it anymore, regardless of how weak you think an article is.
The 'gaming' in question was about getting people to upvote one's stuff. That's against the rules, but we saw no evidence you did it. This is why I chided the user who made that accusation. It's corrosive of the civility we strive for here when people make accusations without real grounds for them.
