Module 3 of 84 min readLevel: FoundationalFocus: Behavior-First Risk Classification

Key Takeaways

After completing this module you will understand the following key concepts.

  • How DefenderNet standardizes violation categories
  • Why a behavior-first approach enables earlier intervention
  • The difference between predatory behavior and CSAM/CSEM
  • How standardized reporting strengthens cross-server protection

The behavior-first approach

One of the most important skills for moderators is knowing how to recognize and classify harmful behavior clearly and consistently. This makes enforcement easier, consistency stronger, data more reliable, and protection better across every community.

These categories are designed with a behavior-first approach. That means moderators and communities do not have to wait until explicit material is shared before recognizing and reporting harmful conduct. For example, any behavior intended to sexually manipulate, exploit, or harm a child — including grooming, coercive communication, the creation or editing of images, the promotion of harmful stereotypes, or the formation of inappropriate relationships with underage users — can be flagged even when no explicit content is shared.

This recognizes that the intent and behavior itself are harmful and dangerous, and allows communities to act at the earliest stages.

CSAM/CSEM as a standardized category

Important

If any of this content brings up difficult feelings for you, please speak to a trusted adult or contact a support service in your area.

CSAM/CSEM is more explicit and severe, covering any visual or descriptive material that depicts child sexual abuse or exploitation. This includes photos, videos, audio, live streams, computer-generated or illustrated depictions that appear realistic, or even textual content such as stories of child sexual abuse and exploitation. Possession, sharing, or linking to such content is illegal.

By treating CSAM/CSEM as a standardized violation category, DefenderNet ensures that any report involving this material is escalated immediately to the appropriate authorities while also preventing repeat offenders from moving unnoticed between servers.

Communities gain two key benefits

Moderator clarity

They know exactly how to classify and escalate behaviors — including early behaviors that might lead to further harm — that may otherwise be misinterpreted or downplayed.

Network resilience

Reports build into a shared body of intelligence that makes it harder for individuals who commit acts of sexual abuse and exploitation to continue harming children across different platforms.

This behavior-first approach is vital. It empowers communities to act on intent and grooming behaviors before they escalate, while ensuring the most severe cases are flagged and dealt with properly. In doing so, DefenderNet does not just respond to harm after it happens — it actively helps prevent it.

How does DefenderNet support this?

DefenderNet uses standardized categories to help communities classify and respond to harmful behavior consistently. This makes it easier to act early, share signals across communities, and prevent repeat harm.

When harmful behavior is identified, moderators need to decide how to respond. This typically involves three actions: restricting access (ban), documenting/reporting, and escalating when necessary.
