I recently asked in the SO.pt Meta about some edits made to my questions and answers where I wasn't notified in my inbox.

To test the "theory", I asked someone with a gold badge in a tag that I used in my question to make an edit in the question and the answer, and I did not receive a notification after editing.

The question was:

Converter objeto em json no php

and the answer was:


The user that edited has a gold badge in the PHP tag on SO.pt. Is this rule applicable for the whole SE network? That is, edits made by someone who has a gold badge in one of the tags do not notify the OP?


I asked two members without a gold badge (in the question / answer tag) to do the same, and received notifications, as can be seen in this screen shot:

    This got nothing to do with gold badge, that's for sure. Commented Apr 6, 2016 at 13:24
  • @ShadowWizard I auditioned with 3 members, and only what had gold badge, I did not receive notification.

You didn't get notification because nothing was actually changed.

As Kevin says in this answer, the criteria for notification is:

a non-trivial edit was made to a post

And mentions in a comment what is "non-trivial edit":

a non-trivial edit is one which changes at least 10 characters (this is using a diff algorithm, so it's not a simple add/delete; and is naturally a little fuzzy). For the "technical" sites (where code highlighting is enabled) changes to code of at least 2 characters are considered non-trivial.

Additionally, after some testing, it appears that title edits are also subject to the 10-character requirement.

Now, the edit made by the user with gold badge only added a hidden HTML comment. Nothing was actually changed, as can be seen in the diff view:

Hence, too minor to be worth a notification.

If user without the Edit privilege (usually below 2K rep) edits, then it will always send notification, because it's a suggested edit, and you have to review it. So even if such user suggests that same edit (i.e. adding hidden comment) it pass as suggested edit, and you do get notification.

    You're right, i see others questions that I didn't receive notification and they seem to have non-trivial edits. Thanks :)

  • Still unclear will I get notification if somebody edit 5 characters in the body (not a code) and 5 characters in the title simultaneously. Commented Jan 23, 2019 at 9:03
