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.

I've been hit by this a lot. Don't care to much.
