There's a non existing article among the most viewed articles of the Basque language wikipedia since the 8th of October.
The article in question is "Teratologia": https://eu.wikipedia.org/wiki/Teratologia
It's one of the most viewed articles according to the API but I think that it's quite strange and probably it's a bug.
I found this because I created a website that uses this API's data. It's in Basque but you can check the evolution of the page views of the "Teratologia" article in the graphic:
It has zero page views until the 8th of October as expected for a non existing article but then there's a high number of page views. Isn't it strange?
