It might be useless, but I tried this edit https://it.wikipedia.org/w/index.php?diff=68704385 because googling name + username of that person + "wikipedia" led to the page of the deletion procedure of her article on it.wp (among the top results for the search). This might happen sometimes with mirrors, but is not supposed to happen with the actual site. What am I missing?

Huh; that's weird :/. Would suggest reaching out to Chad or one of the other devops people (Ariel?)
I'm not sure what search you're trying but I did notice that urls like this: http://it.wikipedia.org/?title=Wikipedia:Pagine_da_cancellare&useFormat=mobile show up in Google search results, so that may be an issue.
MediaWiki must add noindex for 404 pages and use robots.txt to allow google to crawl them. btw that's a google issue.
As of today, that doesn't seem to happen anymore - I had checked other times in these months and it was still happening.
