Problem: When there is a spam in Wikipedia and we delete the page, they create again and then we simply protect the title against creation. In Wikidata, this is not possible and a spammer easily moves on a newer Qid and has been a game of cat and mouse all the time.
Proposed solution: Have a way to easily protect an item against recreation under another Qid
Who would benefit: Admins and patrollers of Wikidata. Users of wikidata due to improved data quality
