I've had comments deleted before due to the be nice policy. Won't argue against that - if it's the rules, it's the rules.

However, a few hours ago I posted a comment which I believe did not violate be nice and it got deleted.

It was in this question: Mobile Hydroponics Vehicle

I like the question and I am trying to be helpful. I did an edit to fix formatting and left my vote. I also did a comment which has been deleted. As I recall, these were the exact words, which start by quoting a piece of the question:

"Farmland needed to sustain one person ≈ 5 hectares" - where did you get this quote from? Just curious.

When I came to the question later, the comment was not there. I didn't see any "comments are not for extended discussion" notice. I also did not see any room for this question in the chat.

I have been told time and again that I may come across as offensive. I am curious whether this was the impression with the comment above (I would not be surprised). I just need to know so that I can adjust my manners to what is expected. If it wasn't a case of someone feeling offended, I would like to know what other mistake I may have done.

P.s.: in any case, I made another comment along the same lines, trying to be more polite now.


Comments are second-class citizens, so they may be deleted without any explanation and any reason and no-one will care. They usually are not, but they may.

That said, reasons to delete comments are:

  • No longer needed - in your example, source have been added to a question as a link, so that's probably what happened. Confirmed by Monica Cellio♦.

  • Rude or offensive - this one is obvious

  • A whim of comment author

  • Extended discussion - moderators can move to chat, but only once, and they are not forced to do so, they may simply delete if they feel it is a right thing to do.

  • SPAM & vandalism

  • Totally off-topic

  • et cetera

    $\begingroup$ "No longer needed - in your example, source have been added to a question as a link, so that's probably what happened." Makes total sense. Thank you :) $\endgroup$ Jun 20 '18 at 13:13

    $\begingroup$ To confirm: there was a post-edit "no longer needed" flag on the comment, and a moderator agreed. $\endgroup$ Jun 20 '18 at 23:07
  • $\begingroup$ If not for the actual reason in this case (that the answer to the comment's question was added), then I find this answer here to this question to be distressing, because for example, the person asking the question in this case cares, and I'd care too, because it's an interesting side-question. The idea that mods can/should just randomly delete comments without reason "and no-one will care" is pretty annoying and a discouragement to participation. $\endgroup$

  • $\begingroup$ @Dronz that's the point! On many stack sites "add a comment" was already replaced by "suggest an improvement", because comments and forum-like discussion is a form of participation Stack Exchange model wants to discourage. $\endgroup$
