@cardibach - probably not. Group sex offending will create a significant degree of trauma in a victim, likely CPTSD. The cases of these girls are quite harrowing because the group aspect meant children kept in houses for days, with multiple men coming to rape them. They would have absolutely known they could not leave nor a chance of escape.
Children do recover sometimes from sexual abuse. But the chances of recovery from repeat trauma are far less, and multiple offenders will typically make for far greater trauma.
Offender profiles do matter. It seems that the intelligence and MO of such gangs and the prosecution of men are common across the UK.
