How to enforce a Slack code of conduct: the Content Admin role, content flagging settings and review actions, pausing or hiding threads, admins deleting messages on any plan, and information barriers that block DMs and huddles between groups.

- Certification: Salesforce Slack Administrator
- Exam section: Governance, Security and Compliance
- Study guide: https://www.certifyforce.com/study-guide/slack-administrator

**Official exam objective:**

> Given a scenario, determine how to moderate conversations that violate an organization's Slack code of conduct.

## What the exam expects

- Delegate flag review with the Content Admin system role instead of an admin role.
- Configure flagged content review: content types, the policy link, restore and notification options, and the EKM exception.
- Predict who can flag (not guests) and where a flag on an external person's message goes.
- Choose between pausing and hiding a thread, and act on flagged profile content.
- Remove a single message on any plan, and block DMs and huddles between groups with information barriers.

Key terms:
- **Content Admin:** the system role that reviews flagged content and moderates content in an Enterprise org.
- **Flagged content:** messages, profile content or conversation details that members submit for admin review.
- **Pause replies and reactions:** a thread action that stops new replies and reactions but leaves the thread visible.
- **Information barrier:** a block on DMs and huddles between two IdP groups or org-level user groups.
- **Enterprise org:** an Enterprise organization (Enterprise Grid or Enterprise+ plan); flagging, moderation and barriers exist only there.
