The self-described PhD chemist said that while Reddit remains "passionately dedicated to free speech," the climate-change skeptics on the site's /r/science forum were refusing to engage in meaningful discussion. “After some time interacting with the regular denier posters, it became clear that they could not or would not improve their demeanor,” Allen says. "As a scientist myself, it became clear to me that the contrarians were not capable of providing the science to support their ‘skepticism’ on climate change.”
About half a dozen content editors will now moderate the forum's 4 million subscribers. “As moderators responsible for what millions of people see, we felt that to allow a handful of commenters to so purposefully mislead our audience was simply immoral,” Allen adds.
