A provocative dating app designed to let women anonymously ask or warn each other about men they'd encountered rocketed to the top spot on the U.S.

Tea, a dating safety app which allows women to anonymously give men red or green "flags," says it had more than 70,000 photos stolen in a data breach.

The app confirmed that roughly 72,000 images were exposed on the controversial imageboard, including 13,000 selfies and pictures of official photo ID.
