Reddit's science feed has banned climate-change skeptics from making comments in the online forum.
Nathan Allen, the moderator for the forum/r/science, said that climate-change deniers were constantly arguing with "cherry-picked data and conspiratorial thinking."
Allen said that global-warming skeptics acted unruly in the forum, which offers its 4 million subscribers a place to debate recent, peer-reviewed scienctific publications.
"After some time interacting with the regular denier posters, it became clear that they could not or would not improve their demeanor," Allen said in a blog postfor Grist.
Allen's post — entitled "Reddit’s science forum banned climate deniers. Why don’t all newspapers do the same?" — argued that the forum was for educated, scientific debate, not the baseless arguments that he accused climate-change deniers of using.
