An investigation involving almost 2,000 children and their online experiences has been in progress since 2011 in the UK, it has been exposed.
Sky News, by issuing a Freedom of Information Act request, uncovered that 1,200 were then either fined, given a caution or charged with an offence.
20,000 adults were also questioned during the period, of which 11,292 experienced some sort of police action.
A wider picture could not be established due to eighteen police forces' inability to provide data on online abuse.
34 forces around the UK did reveal the number of investigations conducted under Section 127 of the 2003 Communications Act though.
Abuse within social media, unwanted phone calls and text messaging is all covered by the law.
Hertfordshire Police looked into 1,042 cases last year, compared to 751 in 2011.
The Metropolitan Police investigated 2,099 instances over three years – the highest figure across the period.
