"We don't allow anyone, including elected officials or public figures, to share misinformation about Covid-19 that could lead to imminent physical harm, or misinformation that could lead to Covid-19 vaccine hesitancy," a spokesperson for Meta, the company that operates Facebook, told RNZ.
"People who repeatedly breach these policies will have restrictions placed on their page, if removals hit a certain threshold we will remove the page. We strongly encourage people to report content, so we can review it and take appropriate action."
However, Facebook would not comment on whether Grey and Tait had been banned from the platform, or why.
Debunking Conspiracies Aotearoa said it had been frustrated by Facebook's response to disinformation and misinformation related to the pandemic.
"We are all pretty frustrated that no matter how many times we report harmful content to Facebook it is ignored and these recent bans are far too late as major influencers have already done a lot of damage," a spokesperson said.
"We are unsure why Facebook are not so willing to act on these people despite their claims of tackling Covid-19 misinformation. Many of the major people in fact seem to be amplified and come up in video feeds all the time."
It appeared retaliatory campaigns to report posts by Debunking Conspiracies Aotearoa en masse were being organised on Telegram, the spokesperson said.
"Our page itself got done for spam. Facebook gave us no way of challenging it even though it was a post against disinformation," they said.
"We are keeping an eye on NZ-targeted Telegram pages too, which of course are even worse, but if Facebook had taken action early on many people would not have been pulled into these echo chambers where they then encourage them to move to these more extremist platforms."
