We need to stop child abuse in the first place by knowing what to look for within how a child may behave, what they say, do etc. So we can intervene and stop abuse happening.
This goes for
Sexual
Physical
Emotional
Neglect
and now bullying
All indicators of abuse, better child protection training and people reporting but once reported it leads to a child being safeguarded and not due to lack of action allowed to slip through the system.
Children need to know if the ask for help they will get help
Adults need to know if they take a disclosure or have a concern this will be acted on when passed on

Abusers need to know that the law Wil come down on them with FULL FORCE
Getting the balance between protecting children from abuse, protecting activists in oppressed countries from their government agencies and being able to fight conspiracy theories is much harder, we need encryption to protect minority groups but that same tech is used by criminals to share images of abuse for example.
With child abuse we use better child protection
with conspiracy theories we should perhaps use education
with online fraud, better awareness so people avoid being a victim
At the same time lets raise awareness of why encryption is vital for some minority groups living in oppressive countries.
One of the reasons we need to target people traffickers causing more misery , rather than trying to stop people on small boats crossing bodies of water (e,g English channel) the traffickers are the issue and as you said this trafficking of children is linked to child abuse and the production of child abuse imagery.
