The user created a Wikidata item linked to Abubakar Usman Gurbin Bore three times, so I assume they were also the one who created the Wikipedia article in all three cases, then they created Abubakar Usman (which someone else moved to Draft:Abubakar Usman), and that page links to the same domain which was mentioned in the previous investigation.

Article creation of Abubakar Usman HCE. I see here that User:Salvidrim! protected the page for sysop-only creation. What a great idea to choose another article title to get around it - not really. --JustBerry (talk) 19:55, 5 October 2015 (UTC) JustBerry (talk) 19:55, 5 October 2015 (UTC)

They created Abubakar Usman CE, I think they also created Abubakar usman (now deleted, so I can't be sure, but they created the Wikidata item for it (also now deleted) and they got a deletion notice on their talk page). They made a number of edits to Alhaji Bello Magaji which was created by another sock (User:Mustapha Hashimu) which has already been blocked. Nikki (talk) 00:51, 18 October 2015 (UTC)

Blocked and tagged per WP:DUCK. From what he wrote on his (deleted) user page, it seems he really wants to contribute and is not just playing about; I left a note on his talk page explaining that he is going about things the wrong way. JohnCD (talk) 21:07, 8 November 2015 (UTC)
