YouTube said Wednesday that its moderators had mistakenly removed videos in recent days during what some critics had called an ideological "purge," highlighting the ongoing challenge for a video giant now hiring thousands of new employees in a push to rein in shocking and dangerous content.

Viewers and producers had recently complained that the site was targeting right-wing voices — including some gun-related channels that had posted content in the days since the Parkland, Fla., school shooting — with suspensions, video removals and "warning strikes." The video giant has faced intensifying scrutiny in recent weeks over the content it hosts and promotes, including one video, listed in the site's top "Trending" ranking, that suggested students who had survived the shooting were "crisis actors."
