Can curator privileges and status be revoked?

Yes, sure.

The Lyrics Curators have to set an example for the community. 

Curators can receive (by Slack or by email) different warnings from the Musixmatch Team if:

• They don't respect the writing guidelines
• They are inactive for over 6 months
• They use an inappropriate or offensive language
• They are not available on Slack or if you don't reply to the email sent by the Musixmatch Content Team
• They get a high number of complaints

The privileges and the curator status will be revoked to the Lyrics Curators who have received 2 or 3 warnings.

The following rules are applied immediately when a Curator is not following the Writing Guidelines during Missions.
