Hi, author here. I don't do that. I think I even mention in the post that I don't bother with vote-ringing on HN because I think HN's algos are pretty sophisticated on this front. Plus, HN hellbans a lot for a lot of reasons, so any type of manipulation is extremely risky.
Also, I generally write enough stuff that I don't need any one particular post to succeed, but keeping my domain off any "blacklists" is very important to me. Vote manipulation would be a very, very bad decision for me.

I think the right answer should be that you don't do vote manipulation because it's deceitful and unethical. Your argument here is basically "because I can't get away with it". :(
