Facebook, Snapchat or Instagram most common methods used to target victims.
The social media platforms were used in 63 percent of cases - where communication method was recorded.
Since the introduction of a new anti-grooming law in Wales - there's been an increase in the number of incidents reported.
More than 130 crimes were recorded in Wales in the first six months of it's implementation which was brought about as a result of a campaign by the NSPCC.
South Wales Police saw the highest number in six months with 74 and Dyfed Powys Police with 19.
The NSPCC is now calling on UK Government and social networks to develop technology already at their disposal to prevent grooming, and bring in grooming alerts for victims and moderators.
Tony Stower, NSPCC Head of Child Safety Online, said: “Despite the staggering number of grooming offences in just six months, Government and social networks are not properly working together and using all the tools available to stop this crime from happening.
“Government’s Internet Safety Strategy must require social networks to build in technology to keep their young users safe, rather than relying on police to step in once harm has already been done.
“If Government makes a code for social networks that is entirely optional and includes no requirement for platforms to tackle grooming, this is a massive missed opportunity and children will continue to be put at risk.”
Freedom of Information requests to police forces in England and Wales show that:
- Across the UK 1,316 offences of Sexual Communication with a Child were recorded in just six months.
- Girls aged 12-15 were the most likely to be targeted by predators, and the youngest victims were aged seven.
Three Welsh police forces, excluding South Wales, also provided responses which showed the means of communication used to groom children with Facebook/Facebook Messenger the most common with 31%, SnapChat being used in 18%, Instagram in 14% and Other, including Twitter, in 16%.
The responses also showed that children as young as seven years old were victims of this new grooming offence.
New ways of stopping groomers
Before the new anti-grooming law came into force on April 3 last year, police could not intervene until groomers met their victims. In 2015 former England footballer Adam Johnson sent sexual messages to a 15-year-old girl, before meeting her and engaging in sexual activity. Police being able to step in sooner is an important step, but Government must now act to prevent grooming.
Algorithms are already used by social networks to target adverts at social media users, and to detect illegal content online.
The same techniques must now be developed to:
- Alert children to potential grooming behaviour from adults they speak to online.
- Alert moderators of suspected groomers and enable them to notify police.
'Groomer alerts for children must be introduced as part of the Government's Internet Safety Strategy'
Where children are speaking to adults online, it's possible for grooming language to be automatically picked up using algorithms in order to send an alert to children; allowing them to think twice about the chat they're having and offering them support if needed.
The Department for Digital, Culture, Media and Sport could make this happen. Yet DCMS has said that its Internet Safety Strategy will produce a code for social networks that will only be voluntary, and that code will not include measures to prevent grooming.
The NSPCC is arguing that this doesn't go far enough.
Home Office must work with social networks so grooming suspects can be automatically flagged to moderators.
At present algorithms already automatically flag child abuse images, hate speech and extremist content to moderators for removal. The NSPCC is calling on the Home Office to work with industry to use existing technology to flag unusual account patterns associated with grooming behaviours. For example, friending and following many young people with no mutual friends and no geographic links, getting a high number of rejected friend requests from children, or spikes in views of posts made by under-18 accounts.
