Intelligence agencies in New Zealand are being urged to do a better job at blocking a website commonly used by white supremacists. It comes as a warning from intelligence expert Paul Buchanan who says a ban on the website 4chan is not foolproof, after a threat aimed at two Christchurch mosques was posted on the site this week. A 27-year-old man was arrested on Thursday and appeared in court on Friday charged with threatening to kill worshippers at Linwood Islamic Centre and Al Noor Mosque in Christchurch. Police said he made the threats on 4chan, a website frequently used by extremists and white supremacists. Local internet service providers banned 4chan and the related 8chan, following the terror attacks on March 15 in 2019. But Buchanan said there are still problems. “The bans instituted by the internet providers here in New Zealand is not sufficient when it comes to extremists communicating with each other.”
