Where is nudity description on much movies had gone? like alien resurrection and predator 2018?

Ah, thanks.  We thought the issue you were reporting was that you could not see the Parents Guide at all. IMDb is a user contributed site so if the descriptions are absent from some titles, it means that nobody has contributed them yet.  Please see https://help.imdb.com/article/contribution/contribution-information/adding-new-data/G6BXD2JFDCCETUF4 for more information. 

@forthehorde Thanks, yes, that would also cover it. 

I mean exactly this that during last week nudity description on many movies had disappeared. This ones only some of them. I using this information often and contribute it by myself but someone had deleted previously existed data.

@forthehorde / @zergshadow  Thanks, yes, the team is investigating now. The source of the problem has been identified and stopped.  It will take a while to restore the deleted data. 

Well, I'm slightly pleased to know that, since I'm often not sure if some edits reflect the perspective of the IMDb data editors or just some random, opinionated, rookie contributor. Whenever something is removed, it is not necessarily obvious to me whether or not it was removed for being offensive, but those sorts of things to cause me to wonder about how particular items ought to be reworded. One of the issues with the French film Tomboy is that of whether the main character is better described as a girl or a transgender boy, perhaps alternately referred to only by name. For that reason, and given the lack of feedback, I've hesitated to try to "restore" the IMDb parents guide for the movie, so the corrective mission is sitting on the back burner, so to speak.

What is the matter?
