The Tech Coalition, the group of tech companies developing approaches and policies to combat online child sexual exploitation and abuse (CSEA), today announced the launch of a new program, Lantern, designed to enable social media platforms to share “signals” about activity and accounts that might violate their policies against CSEA.

Participating platforms in Lantern — which so far include Discord, Google, Mega, Meta, Quora, Roblox, Snap and Twitch — can upload signals to Lantern about activity that runs afoul of their terms, The Tech Coalition explains. Signals can include information tied to policy-violating accounts, such as email addresses and usernames, or keywords used to groom as well as buy and sell child sexual abuse material (CSAM). Other participating platforms can then select from the signals available in Lantern, run the selected signals against their platform, review any activity and content the signals surface and take appropriate action.
