Reason for deleting comments?

Question

Several days ago (perhaps week before last?), I posted a comment on this answer:

https://workplace.stackexchange.com/a/36407/16724

As closely as I can recall, my comment was:

This answer is the most generous/gracious/nicest answer here. Although, if you have two of the same cup, how can you tell them apart?

Someone later replied something along the lines of:

Cups like this often come in different varieties, so you could get one that is slightly different.

(That wasn't very close to the text, but that was the basic point.)

Those comments have since been deleted, and I'm very confused about why. My original comment raised what I considered to be a valid point (How do you tell them apart?). I suppose the mention of it being nice/generous/gracious might be considered chatty, but when I originally made the comment, I felt that pointing it out was important since the answer was sitting at a net -4 votes. (I clearly am not the only one to hold that opinion, as it has since received a net +24 votes and is sitting at +20.) The second comment was purely useful; it addressed the concern I raised (or at least attempted to).

Could someone shed some light on the reason for deleting these comments?

Answer 1

There are, at present, 26 deleted comments on that answer. If yours and the response had been the only ones they probably wouldn't have attracted any notice, but they ended up as part of a larger set of comments that had largely descended to arguments about what is or isn't passive-aggressive, assertions and counter-claims that this rewards bad behavior, and some heated comments that were definitely over the "be nice" line. Not yours, to be clear, but many others.

Your comment asked a good question. The ideal response would be for somebody to edit the answer to address that concern by adding a note that it might come in a different color for easy distinction. Comments aren't meant to be long-lived (durable content should be in questions and answers), and in the end, while cleaning up the pile there, I decided that this particular point wasn't all that critical here (other answers address ways to distinguish your mug from others').

That still leaves the part of your comment that said that this is a kind/gracious response. A later comment covered that in a little more detail so I didn't think we need two, so I deleted yours.

There was nothing wrong with your comment on its own; it was just a victim of circumstances. I'm sorry this caused you any upset.
