Dear arXiv-moderation,

This paper is a joke paper: https://arxiv.org/abs/1703.02528 (it was submitted to an April 1st joke conference: http://sigbovik.org/2017).

Could you please remove it from arXiv?

Best,
Spa Mme

This seems to be in contradiction with https://arxiv.org/help/moderation:

arXiv is distinct from the web as a whole, because arXiv contains exclusively scientific research content. Although arXiv is open to submissions from the scientific communities, our team has worked behind the scenes for a long time to ensure the quality of our content.

arXiv moderators will suggest the removal of a submission that violates arXiv policies in some way. Potential reasons for removal are: Inappropriate format. arXiv accepts only submissions in the form of an article that would be refereeable by a conventional publication venue. This excludes […] papers that contain inflammatory or fictitious content, papers that use highly dramatic and mis-representative titles/abstracts/introductions.
