Daniel's uncle, Ron Reilly, 47, speaking on behalf of the grieving family, branded the lack of progress as "disgusting".
Daniel, 17, from Dunfermline, Fife, was tricked into taking part in online Skype conversations with someone he believed was a girl of the same age.
But when a recording of the call was used to try to blackmail him in July this year, Daniel jumped off the Forth Road Bridge. Since then, both the UK and Scottish governments have pledged to take action against cyber blackmail.
The Scottish Government plans to hold a summit on "Protecting Children Online".
An exasperated Mr Reilly suggested it was time for action. He said: "I might have to go to one of these government meetings about child protection online and tell them what I think."
A Downing Street spokesman said: "The Prime Minister has set out a series of measures to keep children safe online."
