A Polish farmer was shocked to see this year’s harvest of potatoes disappear overnight after a viral social media post claimed that he was giving them away because he couldn’t sell them.

A farmer from Dąbrowica, in Poland’s Podkarpacie region, lost 150 tons because of a fake social media post that encouraged people to go to his field and help themselves to his potatoes because he couldn’t sell them and had decided to give them away. Many came to his plot of land to fill their bags with potatoes, but some took tens of tonnes of tubers, essentially stealing the man’s hard work for profit, whether they knew it or not. When the farmer came to check on his potatoes lat Monday, he was shocked that most of the harvested piles were gone.
