You can only downvote on HN after you've acquired enough karma yourself. Bots can't do sh* here, thank you very much.

Do you think PR agencies don't maintain such accounts?

Amazing.

Significant amounts of HN accounts with enough karma to downvote exist which are owned by bot farms.

If you know they're significant, then you must know which they are? Did you report it to admin? Or you just speculate?
