User experience / Backstory
On August 3, I began receiving notifications on English Wikipedia about categories that have been connected to Wikidata items. They appear at https://en.wikipedia.org/wiki/Special:Notifications and look like this:
The page Category:3rd-century Moorish people was connected to the Wikidata item Q55947888, which contains data relevant to the topic.
They do not appear at https://www.wikidata.org/wiki/Special:Notifications
I have reviewed both Wikipedia preferences and Wikidata preferences, I have not activated the "Connection with Wikidata" option in either section.
I am not sure if this a longstanding issue, or if I have only just noticed it because Wikidata user GZWDer (flood) has been exceptionally active lately. I don't recall receiving any such notifications in the past, and in the past 2 days I have received 13 such notifications.
I would like to stop receiving these notifications and I see no option by which to do this. I would expect the "Connection with Wikidata" option at English Wikipedia preferences to deactivate these notifications and it does not.
