Woman fined for Facebook invite to a mass party

WARSAW, Poland—A Polish court has fined a 23-year-old woman who admitted posting an invitation to an outdoor spring party Facebook, which drew more than 20,000 people. Some of them were rowdy and got into fights.

The court in the southern city of Krakow said Friday the woman failed to seek permission or ensure security during the party in April on the city outskirts. One man was injured after falling from a cliff. The woman — identified only as Anna K., in line with Poland’s privacy regulations — was convicted of organizing an unauthorized gathering.

The court said the place is “extremely dangerous” because of its water tank and rocks. It fined the woman 2,400 zlotys ($785).
