This bullying can put young people off using the social media sites, leaving them feeling isolated and lonely, but the problem does not always come from people known to the young person. And sexist abuse online is a specific problem and young women can face sexist and often violent harassment online.
It's a well quoted fact that volunteering has numerous benefits-whether for health, skills development or wellbeing it's an all round great thing to do. Volunteering showcases human beings at their best and we should take the opportunity that volunteers week provides to celebrate and appreciate everyone who gives their time.
he extent of NSA monitoring revealed by whistle-blower Edward Snowden showed that democratic and supposedly "free" governments do already attempt to monitor us. The scale of monitoring required is vast, but the technology is catching up. There are two technological changes that are taking place at present that I believe will fundamentally change our approach to privacy...
As I head towards my fifth anniversary leading the IWF, there is one consistent factor - we're always changing and growing and 2015 was no exception. Today we'll be publishing our latest figures. What stands out, is the dramatic increase in the number of confirmed reports of illegal imagery since we started actively searching for child sexual abuse images and videos.
Cleaning up the internet of abuse images and videos - that in the worst cases depict children being raped and tortured - is a global challenge. The significant achievements of the Internet Watch Foundation (IWF) are crucial in this battle and this week its annual report revealed a staggering 417% increase over two years in the volume of images reported and removed.
We obviously know that social media represents an idealized version of people's lives, but still can't help envying them.

We need to accept that children and young people like to be online and use that as an opportunity to harness the power of the internet to identify and address problem behaviours. As Young Minds suggests, we can productively use online solutions that help young people find help, help themselves and help each other.
Tackling the broader cybercrime challenge needs an orchestrated response. I wanted to highlight three ways in which law enforcement agencies are working with each other and other organisations (including my own) to tackle the real and very present danger represented by opportunistic and organised criminals online...
In terms of pornography, the internet is like giving kids the keys to a gigantic sex sweet shop and then asking them not to look or partake. And this becomes even more hypocritical when you consider it was us, via newspapers, magazines, music, mainstream films and TV that gave kids their very first sugar rush.
This survey of a representative sample of 1,204 schools across the UK found that 30 per cent of primary schools were under resourced when it comes to having a basic broadband connection, and almost half didn't have sufficient Wi-Fi. In secondary schools the picture is a little better, but not by much.
