The pro-life group Live Action is slamming Pinterest for “trying to secretly and dishonestly censor free expression” after the popular photo sharing site permanently banned the advocacy organization for allegedly promoting “harmful misinformation.”

On Tuesday, an anonymous whistleblower at the company told Project Veritas that Pinterest added “” to its “pornography block list,” meaning users could no longer create pins that link to “”

Additionally, “Bible verses” and other Christian terms also are listed on Pinterest’s offensive terms list, a list that employees add terms to manually.

When confronted, Pinterest informed Live Action its page was “permanently suspended because its contents went against our policies on misinformation,” Live Action reported. The note went on to claim Live Action spreads “medical misinformation and conspiracies that turn individuals and facilities into targets for harassment and violence.”

In a statement made available to The Christian Post, Live Action founder and president Lila Rose said the organization has “more questions than answers about Pinterest’s censorship of Live Action and the pro-life message.”

“This does not appear to be a simple mistake,” she continued. “When confronted with an appeal, their employees doubled down and kept on the pornography list.

Live Action noted that, after testing the website, the organization was unable to create pins from their own website, but was able to create pins to other pro-life websites and create pins to pro-abortion websites like Planned Parenthood.

Live Action, which was previously censored by Twitter and YouTube, is now asking people to sign a petition urging Pinterest to “live up to the stated values of your company and the spirit of the First Amendment with consistency and end the suppression of opinions affirming life and human dignity.”

Live Action is not the only pro-life organization censored by Pinterest: the Catholic advocacy group American Life League announced via Twitter it was also “shut out of Pinterest last year.”

According to the whistleblower, someone at Pinterest also added pro-life activist “David Daleiden/Planned Parenthood” to a list of conspiracy theories that it monitors. Daleiden released an undercover video exposing Planned Parenthood for harvesting aborted baby body parts and illegally selling them.

The above comes from a June 11 story on the Christian Post.
