Peter Hasson of the Daily Caller details disturbing news about one of the social media giants.

The Southern Poverty Law Center is assisting YouTube in policing content on their platform, The Daily Caller has learned.

The left-wing nonprofit — which has more recently come under fire for labeling legitimate conservative organizations as “hate groups” — is one of the more than 100 nongovernment organizations (NGOs) and government agencies in YouTube’s “Trusted Flaggers” program, a source with knowledge of the arrangement told TheDC.

The SPLC and other program members help police YouTube for extremist content, ranging from so-called hate speech to terrorist recruiting videos.

All of the groups in the program have confidentiality agreements, a spokesperson for Google, YouTube’s parent company, previously told TheDC. A handful of YouTube’s “Trusted Flaggers,” including the Anti-Defamation League and No Hate Speech — a European organization focused on combatting intolerance — have gone public with their participation in the program. The vast majority of the groups in the program have remained hidden behind their confidentiality agreements.

The SPLC’s close involvement in policing content on YouTube is likely to cause consternation among conservatives who worry that they may not be treated fairly. The left-wing group has consistently labeled pedestrian conservative organizations as “hate groups” and has been directly tied to violence against conservatives in the past.
