Noticing wide scale and consistently poor use of a bot to comment, down-vote, and close

Question

There is a user on this site, who participates in chat, and posts answers and participates in discussions, but based on the speed, frequency, and consistent low quality of the user's comments, I believe the user is using a script to rapidly detect, close, and / or down-vote "poor" questions or duplicates, and has affected the site negatively on a wide scale every day for years now.

For example, I just posted a question:

When trying to learn about proper comment practices, I found a lot of conflicting opinions, and it's obviously a very subjective topic. So I'm not going to ask "Should I comment, or should I not?"

The question I'd like to pose is, for me, as a self taught developer interested in applying for programming jobs in the future, a vital one: Of the two strategies

"Comment the right code in the right way." - (comments where needed)

and

"Instead of writing comments, write more readable code." - (if you need comments, your code is bad)

are both valid strategies in programming?

If I submit an application with code samples including masterfully written code and no comments, are experienced programmers likely to be familiar with that approach?

I'm not asking "Will the specific guy reading my application like my coding style", obviously no one can guess that, I'm just looking for a general answer as to whether both practices are common, or if my code will be seen as terrible across the board.

And in less than 30 seconds of posting the question I received a down vote and this seemingly automated comment:

Possible duplicate of "Comments are a code smell"

• Is my question a duplicate of that question? The answer is very clearly no.

• Is it valid to mark a question as a duplicate of a closed question rather than voting to close? Probably not.

I've experienced this behavior (instant down-vote and either close vote with no explaining comment or improvement suggestion, or poor duplicate claim) from this user consistently across my rare visits to this site over the past few years, and this user's wide scale and poor contribution is the reason I avoid visiting this site, unless I have a question I feel is important and can't find the answer somewhere else.
