In collection search, "collections that likely violate the Guidelines" refers to collections that likely violate our Guidelines and Terms of Use and that our system has automatically detected as possibly making it harder for people to discover collections.
You can choose to show or hide these collections in your search results.
By default, this option is set to "Hide".
You can change it in Search options > Other > Collections that may interfere with search.
Detection criteria for these collections
We set our detection criteria based on our Guidelines and Terms of Use, taking into account multiple factors such as information about the collection, the activity of the person who posted it, and the impact on the search experience.
We'll also review our detection criteria and targets as needed, without disclosing details to prevent abuse. Thank you for your understanding.
