The day before I arrived in Florence, Italy last summer, the guy (and his friends) who had been in my room before me got caught sneaking into another room and jerking-off onto the girl who was sleeping there. The girl understandably flipped shit and called the police, who banned the group of guys (I believe they were Armenian) from the hostel with no other punishment. This story was corroborated by numerous witnesses and when I went on to tell the story, often, to people at other hostels along my journeys, I would sometimes run into someone who had heard about it in passing prior to meeting me.
