Facebook’s quasi-independent Oversight Board is asking the public to weigh in with comments on the social media platform’s cross-check program for some high-profile users.

The Oversight Board opened up public comments on Wednesday as part of its probe into the cross-check system, which reportedly kept certain public figures on the platform, including former President Trump, from facing the full extent of Facebook’s content moderation policies.

The board is asking individuals and organizations to submit comments regarding whether a cross-check system is needed and whether it strengthens or undermines the protection of human rights. The board is also asking for comment as to what additional resources Meta, Facebook’s parent company, should dedicate to improving the cross-check system.

Public comments are due by Jan. 14.
