When trying to understand why administrators were not using the translation notifications extension, one of the major issues highlighted was that the extension was too spammy. It notified users who are no longer active or maybe blocked. We addressed that by fixing T323192: Stop notifying translators who have been inactive for years.
It would be good to have some statistics if the usage of the extension has gone up since then (July, 2023). A very simple way of doing this is to look at Special:Log/notifytranslators and count the number of notifications before and after that date and the unique users who have used the extension to send notification. We can start by doing this for the following wikis:
- Metawiki
- MediaWiki
- Commons
