There are many campaigning for this, in many different countries.
I support this fully.
Get them off the internet, off social media.
Keep children as safe as possible.
Reduce them online grooming.
Reduce these people from harassing abuse survivors.
Reduce them encouraging the child porn industry.
They made a choice to abuse children, or illegally look at child porn.
They should have this ban, as the consequences.
Keep children safer.
The priority, always.
Do-gooders, enough already.
