Just to add a little further complexity. Lots of articles and deleted articles are about people. Names are often not unique, and just because one person with a particular name has had an article on them deleted it does not mean that there won't be a notable person of the same name.
For example I was once asked to restore a particular deleted article so that someone could look at the deleted version before creating an article on a professor who they assured me was very notable and they had plenty of sources for. I had a look at the deleted article, and told them I doubted there was anything there worth restoring, and to go ahead with the article on the professor. I also added that I didn't know if the deleted article was about the same person or a different person of the same name, but if they found that their professor had been a pro skateboarder in his teens, I suggested they give that its own section, and not make that his main claim to notability or have it dominate the lede. In another instance I resolved an edit war over whether an article should be about either of two people of the same name by deleting the article, restoring all the versions that were about person A and moving them to a new clearer name, then restoring the other revisions and moving them to a page with a name that made it clear they were about person B, then I turned the original battleground article into a disambiguation page that listed both people. That would be a rare situation compared to redirects, but I hope it gives you an idea of the complexity of Wikipedia article names over time. When there are multiple topics with the same name the default should be that the primary one gets the name with the secondary topics getting longer names and a mention in a disambiguation page. There are people who get very concerned as to which if any article should be primary, and while sometimes that is as obvious as Dallas, Scotland v Dallas, Texas, other times that can be contentious and even be changed over time. I can remember heated arguments about Perth Scotland v Perth Australia and I dread to think how the Mercury, Atlas and Apollo decisions were made. TLDR Names of articles don't just go through a process of deletion WSC On Fri, 5 Nov 2021 at 18:30, Adam Wight <[email protected]> wrote: > Going back to your original question, > > > which articles are no longer on Wikipedia > > This is easy enough to query in bulk: > > > https://en.wikipedia.org/w/api.php?action=query&prop=revisions&rvprop=ids&titles=Zayn%20Malik|NonexistentPage|Draft:Kajl%C3%A2ngvoj > <https://en.wikipedia.org/w/api.php?action=query&prop=revisions&rvprop=ids&titles=Zayn%20Malik%7CNonexistentPage%7CDraft:Kajl%C3%A2ngvoj> > > The first page exists, but the other two never existed and were deleted, > respectively.
