Emma-Jane Cross, from campaign group BeatBullying, says one in three young people are cyber bullied.
She said: "High-profile cases of trolling over the last week have deservedly received lots of attention in the media. However, we also cannot forget that thousands of young people, as in the tragic case of Hannah Smith, face a daily barrage of online abuse, death threats and harassment.
"Although they may not be in the public eye or have celebrity status, it's shocking that one in three young people are cyberbullied, and one in 13 face persistent abuse online.
"We want internet service providers, schools, Government and the police to come together and produce a UK anti-bullying strategy, to prove that this kind of behaviour will not be tolerated.
"We'd also urge any young person worried about cyber-bullying to visit BeatBullying.org for advice and support."
The founders of the website linked to the suicide of teenager Hannah Smith said they could reveal the names of anonymous bullies to the police.
Hannah, 14, died last Friday at her home in Lutterworth, Leicestershire, after being abused on the social networking site Ask.fm.
Mark and Ilja Terebin, bosses of the Latvia-based website, said the site has the technology to identify "almost all users" and that they are committed to supporting the Leicestershire Police investigation.
They said "in extreme circumstances such as those we've experienced this week" they can use technology to identify those behind the taunts and "ensure this information is accessible to the appropriate legal authorities".
Ask.fm founders Ilja and Mark Terebin said they would create a new website for parents of its users to help them understand the site's functions and moderation policy.
We will create a separate website from the social network to act as an informational resource for parents and others.
This website, besides containing our policies on safety, privacy and moderation (amongst others) will also set out Ask.fm's purpose and values, up to date contact information for the company and the continuing work we will be doing to improve our site.
The father of Hannah Smith, the teenager who took her own life after allegedly being bullying on social media site ask.fm, said his life has been destroyed by her death.
Speaking ahead of his daughter's funeral tomorrow, David Smith has called for the government to do more to protect young people from cyber-bullying, and is angry at the response from the website. ITV News Midlands Correspondent Rupert Evelyn reports.
Ask.fm has announced that it will hire a safety officer to oversee the moderation of questions and comments on the social media site.
Part of a statement released by the site's founders, Ilja and Mark Terebin, said:
We will commit to reviewing all reports made using the report button within 24 hours.
To do this, we will hire more staff to act as moderators, including a Safety Officer to take overall responsibility for moderation at Ask.fm.
The report button will be more prominent on the site itself, and "bullying/harassment" will be introduced as a category alongside the existing categories of "spam or scam", "hate speech", "violence" and "pornographic content".
Users who click this button will be directed to third party resources to help them.
