There has been a massive drop in the number of Irish teens using the controversial web site ask.fm.
The site has faced huge criticism over cyberbullying concerns.
Jim Harding, from Bully4U.ie which carried out the survey, says it has caused them to lose out on Irish users.
Mr Harding said: “I think the high-profile tragedies galvanised the media and the media really took this as a champion casuse and created a lot of awareness.
“That awareness trickled down to schoolchildren, but also schoolchildren are being influenced by their parents.”
The Children’s Minister Frances Fitzgerald has welcomed the news.
