Hi Magnus, on this page with Dutch female saints on nlwiki, generated by ListeriaBot, some (not all) of the redlinks are formatted strangely. Like this one: slaaf - notice that it links to Slaaf (Q-number) rather than just to the nonexistent article Slaaf. Not sure what happens here; a few Wikipedians have already noticed and are discussing it on the talk page. Would be better IMO if no redlinks would point to a page name including a (Q-number). Thanks for looking into this if you have some time!

Strange redlinks from ListeriaBot on nlwiki
I think it's added when there is another article with the nl-label from Wikidata.
That might be it! I tried to wrap my head around it but couldn't find out why it happened...
That is indeed "it". The fact that the item is not linked to a nlwiki article strongly suggests that such an article does not exists. Linking to one just based on the name would likely link to the wrong article.
In the meanwhile, ListeriaBot has been disabled on that page for that reason :( ... I do have the impression, looking at many discussions about Wikidata on Wikipedia, and trying to look at the issue from a non-Wikidata-savvy person's perspective, that we should try to avoid showing Q-numbers on Wikipedia unless someone explicitly chooses to show them. They *are* ugly and totally cryptic. How about changing the process of the bot a bit? Maybe you can link to itemlabel in local wikilanguage (instance-of-label or alternatively subclass-of-label in local wikilanguage) and only use itemlabel in local wikilanguage (Q-number) if no label of the P31 or P279 in the local language is available? That would make it slaaf (bezigheid) in the example mentioned earlier, which looks a lot better.
Is there some rule in nlwiki that limits the choice of article titles (e.g. "if there is a red link, you must use the title of that redlink when creating a new article")?
Once the article is created and linked from the item, the list will refresh and link the new article.
I don't know about the redlink rules in nlwiki, but the actual issue here is that people don't want the Q numbers in the redlinks. I know the bot will refresh (if it's active, heh), but that does not remove the issue either ;-)
@Sjoerddebruin has been so kind to switch the redlink setting on that page to links=text, to accommodate the complainers, but ultimately, I'd personally prefer to have redlinks, really. On my side, I'll try my best to educate people about Wikidata ;-)
