Party and Events Policy

the Airbnb policy state “ Reviews may be removed from the platform for stays where a significant violation of the Party and Events Policy has taken place.”.
I have been traying to understand the conditions are that needs to be met to have this policy allied, without any success. Airbnb refuse to answer and just refer to the content policy, which is a different thing.

I would imagine that the host would need a police report stating that police was called out to break up a party.

Thank you, but it is stated " Information contained in this article may have changed since publication"- The support personnel also do not seams to be aware of this policy. So the question is if it has been revoked ?
