Sexually exploitative images of Chinese women were shared in encrypted Telegram chat groups with hundreds of thousands of users, Chinese media reported, triggering widespread outrage online.

A Chinese-language Telegram chat group named ¡°MaskPark tree hole forum¡± shared images of women secretly taken or filmed in locations, including public toilets, with more than 100,000 anonymous users in China and overseas, said Chinese state-run newspaper Southern Daily, which first reported the chat groups¡¯ existence last week.

Some users posted private images of their current or ex-girlfriends and female family members, the report said, and that some footage of women secretly filmed using pinhole cameras in public spaces was being sold in the chat groups.
