> So we just go around downvoting comments we don't agree with?

Is this that surprising at all? Discussions about this have been on reddit for years. This is the internet. No one owes anyone a civil argument or even a response, and a lot of bad faith actors are out there.

> Paranoid? Really?

Yes. I would categorize a comment that claims a lack of response by someone who downvoted you is assumed to be paid by Russians as paranoid.

EDIT: I'm not quite sure how seriously to take this exchange considering you both deleted the comment I was referring to in addition to responding on a comment I made on a post over a week ago on a completely unrelated topic.
