To be honest I don't care if someone is ired or not, being ired is a choice and usually doesn't depend to what other people do, but how we react to them
It is my understanding that over the years people have developed various software to follow threads and users' comment streams so it is conceivable that some bored zealot took it upon himself to police every single thing you post in real time. Or set up a downvote bot as others suggested. There are some genuine weirdos here.
I haven't been here for a few years (green account again, yay), but at least back then, moderators weren't know for f...ng with anyone like that. Warning, maybe another warning, shadow ban and good bye.
At any rate, posting "@moderators" in the middle of a 4000 comment thread will get you nowhere. There is a contact email at the bottom if you want to ask for investigation.
I've never heard or seen anything like what you suggest.
It has been admitted I think that one is aware of certain bots (not affiliated with YC) that vote in certain directions.
I think I have even seen one popular HNer admit that he thought there was a bot who would upvote all his answer irregardless of who low quality they were.
Maybe someone has something like that and have pointed it at you.
More likely though you annoyed someone and they went in to your profile and looked at your other answers.
Edit: I looked into your comments and here are two notes.
1. Your comments are a mixed bag. Saying Trump brought war to American soil for example isn't anywhere near true and also inflammatory.
2. Some of them are insightful but ires one side without delighting the other. The result is you get a downvote from those who are annoyed and no support from the other side.
It was a simple question, I had the last 6-7 post immediately downvoted at zero points upon submission.
Seconds later.
Unless someone is tracking me , which would be rather incredible, I wanted to know if I triggered something.
Have you ever heard of people shadow banned without warnings?
A post among many to explain what I mean
It's ok if the moderators do their job the way they are told to, it's more of a problem if you don't know why and especially if it happened to you
