i strongly believe that sasaengs should stop. bts are humans too and they deserve the privacy. they do what we want so why shouldn't we do what they want? 
you will probably hear me rant about this a lot. because i am very disappointed in these sasaengs. you violate their space and privacy which makes them feel uncomfortable. they are wonderful people, and we all support them as much as we can but sasaengs do it too much. REMEMBER TO RESPECT EVERYONE YOU MEET!
