To reduce vandalism we need to:
- identify all the Wikipedias that show links from some articles to their corresponding Wikidata items,
- find the best way of hiding these links from those users who can't edit the articles (i.e., non-(auto)confirmed users on semiprotected articles) but only to those users (T208315), and
- apply the necessary changes or get them applied to all the identified Wikipedias.
