Twitter a 'particular challenge' for plans for online pornography age checks

Thinktank that helped ministers draft rules to verify ages says it is unlikely site would be blocked

Twitter and other social media companies have so far refused to engage with the government's plans to introduce age checks to limit underage access to online pornography, an organisation that strongly influenced the rules has said.

Lord Erroll, a crossbench peer who chairs the Digital Policy Alliance (DPA) - a thinktank that has collaborated with the government to draft the rules on age verification (AV), admitted the ultimate sanction intended for sites that fail to implement AV is unlikely to be applied to Twitter.
