I will note that the revert message is decided by the wiki. So for example, the English wikipedia message will not send out such pings. Nor will Spanish.
It will for French and Hindi.
Etc.

We can probably ignore the entire message in case of reverts. @MaxSem knows more about it than I do.

Yeah it looks like mediawiki.org is using the default message, while enwiki and others have a customized one.

For the time being I've manually updated the message on mediawiki.org, so you shouldn't get pinged anymore.

It appears reverts are ignored when the "undo" method was used, but not when "rollback" was used. This seems like an error, since they were supposed to all be ignored per comments on the parent task (T32750#3997501).

It seems that the $undidRevId parameter is not passed to the 'PageContentSaveComplete' hook when rollbacking, but Echo code assumes it is.

Yes I think you're right.. let's focus on fixing that? Nevermind updating the messages =p

Jumping on the bandwagon here. I'm getting way too many emails from this. :p

Same here. It affects bot accounts significantly. For example; my bot (TurkászBot) has the latest edit on many pages, which means I got plenty of notification in short period.

There is the same problem on Wikipedia in Italian, cf. https://meta.wikimedia.org/wiki/Talk:Community_Tech/Ping_users_from_the_edit_summary#Reverts_to_last_edit_by_XXX
There is the same problem on Wikidata: I have been notified for the edit https://www.wikidata.org/w/index.php?title=Q1420&oldid=prev&diff=650083501

I suspect that it comes from https://translatewiki.net/wiki/MediaWiki:Revertpage ...and its numerous subpages... but I have no account on translatewiki.net...

<s>Sorry, no. It is correct that people are notified if their contribution was reverted.

Else this should be hardcoded, so local admins cannot circumvent the feature like happened in DE:WP in https://de.wikipedia.org/wiki/Spezial:Diff/175063376</s>

Revoking comment; local community users convinced me that for most users my preference won't apply.

This is not what this task is about. The feature you are mentioning has existed for a long time.

As a workaround for it.wiki, we edited the MediaWiki:Revertpage message to use [[:User:$1|$1]]. Definitely not the definitive solution, but at least it should work until a better solution is found.

New feedback about that issue. That's a bit bothering, like the user mentioned:

That's true that I am quite active, but receiving notifications when other users revert back to a version that I authored is distracting and not requested.

I set up email filters, but I'm having to set up multiple filters for the different languages my bot runs on, which is 13 at current.

I do not understand in these things as you do, of course, so I'm curious: Why do you not just add a colon to the message original text?

Too many messages to update. And because the software change broke this, I think the fix should be made in the feature. If it turns out very hard to do that, then we can change the messages.

If people do want to change the messages in the meanwhile to mitigate the issue, they can do what @Daimona did above -

Maybe the original MediaWiki message could use a colon as well. Depending on local customization just creates more issues, even if Max is fixing the underlying issue in Echo itself.

My gut feeling is that anything in MediaWiki core should not depend on/be affected by an extension (Echo in this case).
And even if we do update the default wording, a lot of wikis have their own modified messages which we'd have to fix anyway.
We're not depending on local customization though. The patch above is to not send out *any* notifications from a non-manual revert, irrespective of project/language.
