The app also became a medium for social change. In a viral campaign titled "Feni Without Felling" (2023), it educated users about the importance of preserving cashew trees for biodiversity. Funds from 18+’s "Eco-Labels" (eco-friendly Feni bottles) were used to plant new groves in drought-prone regions. Not all was smooth. Critics questioned the app’s unregulated access to unrated content in a country where alcohol marketing remains a contentious issue. Yet, 18+ doubled down on responsible usage, introducing AI filters to block underage users and a Digital Sober Coach feature to monitor binge consumption patterns. It also partnered with NGOs to provide addiction helplines via the app.
