Dude, disclose affiliate links on HN please.
If you don't believe in making money, perhaps this isn't the site for you.
The fact that there's an affiliate link has no bearing on that.
If someone's spamming the site with affiliate links, they ought to be banned. If someone posts a link with one from time to time, I see absolutely no harm in it. I think it's pretty clear what's what.
This isn't the place to be using undisclosed affiliate links. Had you disclosed it, I would have happily bought it through your link as it would be a legitimate referral.
