High-profile anti-vaxxer WAG NRLs are among those affected by a crackdown on Facebook's vaccine misinformation.
Shanwell Cartwright, wife of Titans player Bryce Cartwright and Taylor Winterstein, wife of Penright Panthers player Frank Winterstein, both had restrictions on their accounts from the social media giant, according to The Daily Telegraph.
At the beginning of this month, Facebook, which owns Instagram, announced that it was moving to eliminate anti-vax messages promoted on its platform by excluding groups or pages from recommendations and reducing their distribution in news feeds and searches .
Both Cartwright and Winterstein were unable to create permanent posts on Instagram or Facebook for two weeks.
However, Winterstein returned to Facebook and posted his 17,000 followers on Instagram this morning after he claimed to be "censored" for anti-vax posts.
"My kids don't deserve to feel the chaos and hostility that surrounds us at the time," he said in his post on Instagram.
"So if you think for a second, I'll allow any nonsense to penetrate our family, think again."
Friday at noon, on the Winterstein Instagram page, earlier this month, there were still numerous anti-vax posts.
He runs the Tay movement's Way, which aims to "mobilize the next generation of parents to regain control of their family's health" and 200 sprinkling anti-vax workshop on its website.
Ms Cartwright was thrown into the media in February after she was made public with her decision not to vaccinate her child, who is now a month old.
In a video, Cartwright told his 9,000 followers that he would no longer publish anti-vax messages.
