L'auteur Robin Laws trouve un cas un peu plus réel de persécution d'un artiste :
Satie wound up briefly imprisoned after sending a postcard to an old guard music critic. The critic had panned Satie's ballet Parade, which had baffled audiences with its contemporary scenario from Jean Cocteau and cubist set design by Picasso. The postcard read simply, “You are an arse.”
The critic charged Satie with criminal libel, on the grounds that his concierge had seen the postcard. (Lesson: seal your imprecations in an envelope, so that the serving classes can't peruse them.) Satie was eventually exonerated, but not before spending several weeks in jail.
La lettre disait "Monsieur et cher ami, vous n'êtes qu'un cul, pire, un cul sans musique". Le critique était un certain Jean Poueigh et Satie passa une semaine en prison en juillet 1917 après ce ballet.
