Aaah, now I know what question you're talking about. I only saw the first version, which made absolutely no sense to me. It was at the top of my active queue, so I posted what I thought to be a very reasonable, 100% snark free comment, asking if you forgot to post a figure or something, as that was what seemed to me to be the problem with the question.
In that state, it was far from an excellent question. I didn't know what R was, I didn't know what C was, and I posted a comment asking for clarification. I couldn't off hand remember if I voted to close at that point, but it looks like I did. I didn't flag it as a low-quality question, though I did think about it, opting instead to see if you could fix it up. In its initial state, though, I did think it was low quality enough to merit the close vote without waiting.
The comment did get four positive ticks, though I can't tell you how long it took. I assure you, those votes did absolutely nothing for my reputation, is far too small of a thing to be capable of stroking my massive ego, and could not help me earn any badges (though if I flagged it as a poor quality question, and it was accepted as helpful, that would have contributed to a badge). I have no sock puppet accounts, and did not flag the comment myself in any way. I asked nobody to upvote the comment (you can check, as the only mechanism I would have to do that would be the group chat).
So, why the upvotes?? I can't speak for the people that upvoted, because I don't even know who they are, but I can certainly say why I might upvote a comment like that if I came across it.
There was a question that I thought needed some help. The comment pointed that out to the asker in a nondisparaging way, judgement free, trying to help a new user form a better question. It even suggested that the shortcomings of the question might be a simple oversight, as opposed to a poorly framed question. Indeed, I would go so far as to say that the comment was completely in line with the "be nice" attitude encouraged by Stack Overflow. It's how we encourage users to interact with new users. The upvotes might be a "well done" indicator, perhaps even by a moderator or two, because that's how we want experienced users to behave.
Believe it or not, a good deal of thought went into framing that comment. Often, I would vote to close and move on. One of the main motivations for that comment, and the wording that I chose, was actually because I thought your question might attract less well-framed comments that you might take offense to. I thought I'd use the opportunity I got by seeing your question fairly early to shut down anybody who might respond more rudely, by showing them how you can solicit more clarity without being rude.
I'm sorry your intro to EESE was rough, but you're certainly welcome to keep at it if you're willing. I hesitate a little to say that, even with the edits, I still need some more context to understand your deleted question. If you want, you can edit this meta question to let us help you make it a better question so you can undelete it and maybe get it upvoted and reopened.
