Using a logical approach, within GB & Rep. of Ireland I would suggest the opportunity has decreased - much higher levels of record-keeping both electronic and written; closure of large-scale childrens homes and orphanages; electronic immigration records; lower rates of adoptions (previously a major 'trafficking' flow); NHS electronic records etc.,
I have done lots of training for a previous and a current job/volunteering roles which involve safeguarding, domestic violence and child safety. Unless a child is smuggled into the UK without anyone noticing it is incredibly hard for a child to live 'under the radar' here now (as the current trial of the couple who went on the run with their undocumented newborn shows).
Since the 1990s and the awful Victoria Climbié case (a trafficked child), then the Soham murders (unvetted staff), I would say comparably fewer minors are now trafficked within/into the UK.
Youngsters may be drawn in' or 'recruited' or forced into some terrible practices like CSA images/film (often by family members) or drug dealing gangs and the like but there is very little 'child trafficking'
per se to use the original meaning.
Developing countries and regions are the main traffickers of children, with 100,000s being exploited in the continents of south America, Africa & the Middle East regions. Even then, it's not usually a case of 'child stealing'

While cases of child trafficking are detected in all regions and in most countries in the world, in Central America and the Caribbean, North Africa and the Middle East, and Sub-Saharan Africa, children account for the majority of identified victims.
Children are particularly vulnerable to human trafficking for several reasons, including poverty, lack of access to education, humanitarian crises, or the lack of support networks.
“Traffickers are known to prey on children in vulnerable situations, especially when their parents or guardians struggle to support their households. This places children under pressure to contribute to the family’s income,” explains Mutasa.
The UNODC anti-trafficking expert says, in many cases, the traffickers are known to the child’s family and guardians or they target children without parental care, including those in orphanages and foster homes. Criminals take advantage of these situations to deceive children and the adults who care for them with “fake promises of better opportunities”.
“In some cases, family members even play a role in the trafficking process, especially in the initial stages. Our research suggests that the extent of family involvement in cases of child trafficking is up to four times higher than in cases of adult trafficking,” he says."
All his former websites are down as well. I respectfully suggest that maybe he is engaging with some therapy or treatment as one possibility amongst others.
