Roughly an hour ago, I wrote a comment on this question. It wasn't offensive, I was merely pointing out the similarity with the arcsinh function and the obvious change of variable that it allows. An hour later, it has been removed. I know the rule is to avoid answering in a comment. This wasn't an answer, as far as I can tell. Is this fair game now?

    $\begingroup$ All comments should be seen as ephemeral. Comments which do not seek to clarify a question are likely to be deleted relatively quickly, and comments which do seek to clarify a question or answer will (hopefully) be deleted once the advice offered is incorporated into the post. As I saw it, your comment gave a hint towards another possible solution. Moreover, that hint had already been incorporated into another answer. Hence there seemed to be no reason to keep the comment around any longer. $\endgroup$

    $\begingroup$ I see. Thanks for taking the time to answer. This is no longer the site I discovered with joy in october 2012. I have felt a tendency, for several years now, towards increasing aggressiveness and authoritarianism. Strong words, but it's how I feel, and this goes much farther than erasing a comment. I have tried to convince myself that I must adapt to the new rules. I have tried to pretend it doesn't matter, but it does. I'm no longer in a position to contribute serenely to this site, therefore it's better that I stop. $\endgroup$ May 10 at 20:19
  • $\begingroup$ Well, I admit to being one who thinks hints as well as answers should not be posted in the comments in the first place--and thus deleted when they do appear. It--the hint-comments and answer-comments that is--tends to discourage people from posting a proper answer. There are also those of us here grumbling that MSE has become too much a homework-helping site you know, where banal questions are burying the good questions, and I think that the comment-hints and comment-answers have a lot to do with this. With that said Jean-Claude Arbaut, I do hope you stick around. $\endgroup$
