Owing to an episode of serious air pollution in recent weeks, Hanoi has at times topped the list of AirVisual’s “major city ranking”, a live pollution ranking of around 90 major global cities. This has helped to raise awareness of air quality issues in Vietnam. However, AirVisual has also become the target of a coordinated campaign in Vietnam to discredit us.
AirVisual has received abusive and threatening messages posted on Facebook and on the Apple App Store and Google Play Store. Consequently, the AirVisual apps and Facebook page are currently no longer accessible in Vietnam.
This is not the first time that revealing the level of air pollution in a city has created fear and led to attacks on the AirVisual community. Our millions of air quality data contributors and community members have always strongly supported our mission to raise awareness of air pollution around the world, and we would like to give a heartfelt thank you to the people in Vietnam who have taken the time to share with us their kind support during this time.
We are receiving thousands of support messages via Facebook, email, our website and app reviews and this support is essential as we are working with Apple, Google and Facebook to confirm that we have been unfairly attacked and helps us to make the AirVisual apps available again in Vietnam.
