Every comment you've made has been about publii - leading me to believe you're associated with it. HN is supportive of people pitching their products - but I would suggest you disclose your association in comments - otherwise it's just plain spammy.
Yes, you are right. I use and love this app. I'm trying help publii team to promote their product. Their team is just two people, so any help is appreciated, especially that this is free, open source soft. What wrong with my comments? There are only a few and always on the subject. I don't understand your point of view.
Unless they're your competitor and you're trying to make them look bad, this just isn't an effective way to shill a service on HN.
