There has been renewed calls for the ban of website ask.fm - after the suicide of an English schoolgirl is being blamed on the site.
Hannah Smith from Leicestershire took her own life on Friday after being taunted on the question and answer online forum.
The site was named in the wake of a number of suicides here last year - including the death of Erin Gallagher from Donegal and Ciara Pugsley from Leitrim.
Ask.fm - which is based in Latvia - said that it encourages users to report incidences of bullying.
Simon Grehan of Internet safety site, Webwise, said the website allows people make comments without identifying themselves.
"Facebook has a real name policy so you have to be who you are on it," he said.
"Twitter doesn't really but most people will adopt if not their real name a pseudonym that will be identifiable but the real selling point of ask.fm is the cloak of anonymity."
