What research are you looking for?
The premise of this entire thread was the OP saying she'd found out a neighbour had been convicted of CSAM and she was sickened and didn't want him near her or her DC.
But her DC were never at risk of CSA from a man she just talked to in the street occasionally.
Which led to lots of posts saying OP should move to protect her DC and some saying tell everyone local and that's informing people and others saying tell everyone local so he's hounded out.
DC are extremely low to risk of CSA from strangers who do not have access to them.
DC are at risk of CSA from people who do have access to them who are usually trusted individuals by the parents or caregivers.
So anyone worrying about the paedo down the street are statistically more likely to have their DC abused by trusted individuals then the paedophile down the street.
And all the research around consuming CSAM suggests there is an increase risk of contact offending though many do not commit contact offences or consider doing so but again, the likelihood is of committing contact offences against DC they have access to
So everyone needs to be aware of the staggering rates of CSAM consumption but don't need to worry about the neighbour who their DC don't come into contact with, but worry about the people they trust
I don't understand what's so controversial or CSA apologetic about that.
They're just facts.
