its so that when their mommies are looking over their shoulder, they dont see any offensive thread titles
because every mom has to protect their kid from reading "fuck", yet the mom probably says it at the kid from time to time
and when the mom isnt in the room, the kid opens the thread and none of the words are censored.
win-win: moms think their kids have good language, and 12 year olds get to see their favorite swear word written out, because they seem to be amused by that
