You have to keep in mind that brainfuck has been invented by a Swiss student. There are 2 clues. Student is obvious. Being Swiss might not be but is one.
People not living in an english speaking country have a different appreciation of swearing in english as they are exposed to it differently: appart from our english classes at school we learn and hear english mostly in songs, movies, TV shows, even modern literature. We are pretty much inundates by the f-word which makes it more an innocent word than in britain and us english.
A few days ago I was doing some cleaning in the house. Usually I rather put music but this time I chose a tv shows instead. Bad idea, it makes you much slower. Bottom line is I chose action-drama Banshee randomly. It seems they literally say fuck or motherfucking every 30 seconds!
So my advice would be: before complaining of people living abroad and using the f-word, maybe you guys should clean your house and stop putting the f-word in every fucking piece of media you sell all over the motherfucking world.
Also swearing can be cultural. For example wear I live in Spain swearing is part of the normal language. Grandparents all say words like coño and de puta madre all day long and nobody seems to blink when their 4 year old kids do the same.
