up until now, BTS has been lucky not to have very many (if any) fans that would be considered sasaeng fans, and I'm very, very happy for that. but their increasing popularity means that there's an increased chance that those kinds of fans will begin to pop up within the fandom. and sasaeng fans treat things like this as a competition--they always want to have the juiciest information, the most invasive personal details. if we as a fandom show people that we WANT to consume BTS' personal information (like their passport photos and details), that only encourages people to obtain and spread it.
