YouTube's new moderators, brought in to spot fake, misleading and extreme videos, stumbled in one of their first major tests, mistakenly removing some clips and channels in the midst of a nationwide debate on gun control.

The Google division said in December it would assign more than 10,000 people to moderate content after a year of scandals over fake and inappropriate content on the world's largest video site.

In the wake of the Feb. 14 school shooting in Parkland, Florida, some YouTube moderators mistakenly removed several videos and some channels from right-wing, pro-gun video producers and outlets. 

Some YouTube channels recently complained about their accounts being pulled entirely. On Wednesday, the Outline

highlighted accounts, including Titus Frost, that were banned from the video site. Frosttweeted on Wednesday that a survivor of the shooting, David Hogg, is an actor. Jerome Corsi of right-wing conspiracy website Infowarssaid on Tuesday that YouTube had taken down one of his videos and disabled his live stream.
