Notes from the digital underground
Telegram’s privacy policy means it doesn’t monitor messages in private chats or private groups and its moderators can only remove content shared on public channels. This translates to there being no mechanism to prevent the distribution of illegal content in private chats.
Criminals are known to have frequently exploited Telegram’s lack of checks on private interactions. Dark web users can create private channels and groups to offer weapons and fake documents for sale. As a rule, they place ads with photos and links to sites on the dark web where you can pay in cryptocurrency.
Telegram has been here before — the platform was removed from the App Store for 24 hours in 2018 due to its failure to crack down on child pornography. Durov assured Apple that he would take care of the situation, however, and the app returned to the store the following day after Durov removed illegal content flagged by Apple.
