An urbanist movement in Warsaw grabbed headlines in Poland when it shared adverts for a new app that purported to allow users to rent out their toilets for a fee.

“We all have basic physiological needs,” the advert for Airpnp (Air Poo and Pee) read. “Many of us have trouble using public toilets. It is often difficult to quickly find a toilet that is near or clean enough. Now you don’t have to worry about that anymore.”

It’s unclear how many went to download the app or were put off by the multiple hygiene-related issues the concept throws up.

Regardless, the app was later revealed as a fake. It was all a stunt to highlight an alleged lack of public toilets in the Polish capital.
