In a question I asked few days back a user named ajay(with 1 reputation point) answered my question which was flagged for deletion by me and then user Izzy added a comment on behalf of ajay and flagged his answer for deletion. Since it was more like a comment rather than an answer, the solution provided by ajay was deleted yesterday. But the exact answer is seen now as a comment from ajay under my question.
Considering a user has to get to gain 50 reputation points to get the commenting previlege. How is this possible for a user with one reputation to comment? Does the user allowed to comment or Is it something that a moderator has an option/tool that has converted the answer to a comment. Because it is shown as commented 4 days back but I haven't seen the comment yesterday. I have no idea how can this happen so, Can some explain this to me?
And how these comments that are converted from answer to a comment ordered? Is this added as the last comment to the question or does it have some ordering based on timestamp?
In my case that ajay has answered(11th July) before user @Izzy commented(14th July). So that I thought ajay's comment is visible before Izzy's comment based on timestamp. I'm confused on how the ordering of comment is based on and does diamond mods have special priorities on the comment section?
