Why that warning tag for this newly released movie page? edit

Curious about the tagline “This article may have been created or edited in return for undisclosed payments,..” how can we sure that this was written after some payments, all I saw was a page for a recently released movie. In fact there isn’t any subjective description or hyped content in that page. I am asking only to understand the underlying guideline if any for that tagline. Thank you.
