I used to think that, when I'm not the author of a post, I'll only receive a inbox message as a reminder for a comment if I've commented under the post and another commenter under the post adds a @xzczd in his comment, but recently I found there seems to be some exceptions, for example, I received a reminder for this comment, no "@" therein.

So in what cases will I receive the reminder for a comment? This seems not to be explained in the helper center, I believe it has been explained somewhere else but failed to find it.

  • Is anything here (How do comment @replies work?) of any help?

  • @MarcoB This is a good summary for the usage of @, but it seems not to address the issue I mentioned above.

1 Answer 1


The second bullet point in the first answer to the post I linked in my comment mentions the following (emphasis mine):

"Note if a user comments on their own post and there is only one person who has previously commented, then that person is also notified if @name is not included."

I think that describes what happened to you:

  • You were the first to comment on Jane Doe's post
  • then Jane Doe commented on her own post right after you,
  • which triggered that rule and you got notified even without @.

The system assumes that the post author is responding to your comment since it's the only other earlier comment there, even though a ping handle has not been included.

  • Oh, I overlooked that line!… Thx for pointing out.
