I have this habit, of making snide remarks on questions of poor quality. In the vast majority of cases the question ends up being closed anyway, and I only add my comment after the question has started receiving the close votes, so its fate is more or less known. But still, there appears to be a problem.
For example, there is this question asking how to learn microcoding, to which I added a comment saying "you begin by finding a micromonitor and a microkeyboard". The question already had one close vote and two downvotes at the time I added that comment, and @gnat had already added the standard comment saying "career and education advice is explicitly off-topic per help center. See meta.programmers.stackexchange.com/a/6488/40980".
I know comments of this type are not a good idea, and I should refrain from posting them. Usually they point to some of the issues of the question, instead of being purely joking, as the above example is, but I agree, they are nothing but a habit that I should kick. But please read on, I have something to ask which has to do with how this web site works.
So, it appears that some moderator has actually gone into the trouble of removing that comment of mine.
Which is fine, I am not complaining about it, as I said I know I should not have made that remark in the first place. My issue is of an entirely different nature.
Here is the rub: I did not receive any notification about the fact that my comment was removed.
This is not a one-off kind of event, the other day I had done a similar thing, and it was the first time I begun to realize that there must be moderators on stackexchange who go around removing inappropriate comments. And then it downed upon me that these snide remarks of mine may have been axed by moderators for years, and I would not know, because I have not been receiving any notifications, nor do I remember every single post on which I once left a snide remark to go see if it is still there.
So, I would have probably realized that these comments are not welcome on stackexchange a lot sooner if I had been receiving notifications about such instances of moderation events, and many of these comments would have never been posted in the first place if I had received notifications the first few times I wrote comments of this kind.
So, shouldn't there be some kind of notification sent when comments are removed for reasons of inappropriateness?
So, this is worse than I thought. If it is possible that a comment containing useful information may be deleted, then I believe that a notification should really be sent, and it should contain the original text of the comment, in case the OP has a use for it.
