Links added on translateable pages result in multiple notifications, for every language that the page is translated to.
In this edit: https://www.mediawiki.org/w/index.php?title=Skin:Modern&diff=2313546&oldid=1820296 Krinkle added a link to https://www.mediawiki.org/wiki/Separating_skins_from_core_MediaWiki, which I authored some years ago, generating a notification for me that the page was linked. This is great.
However, I subsequently received 15 more notifications when this edit was propagated to all the translated versions by FuzzyBot (e.g. https://www.mediawiki.org/w/index.php?title=Skin:Modern/ru&diff=2313581&oldid=prev). This is really quite silly.
