The search request is received from a client device. The search request requests the listing of candidate user profiles corresponding to a search query. The listing of candidate user profiles corresponding to the search query is determined. A trained spam detection model is applied to each of the candidate user profiles to identify the set of spam user profiles. The demoting of the spam user profiles is performed. The listing of candidate user profiles is communicated for presentation in the search user interface, the presentation reflecting the demoting of the spam user profiles.
