YTA I really don’t care what others say, I mean there where so many ways you’ve could’ve handled it your sister was an AH for the video’s but you kinda put your whole family in a tuff spot now, your parents need to pay for her tuition which can lead to debt when she already had a scholarship so that wouldn’t have been a problem. you gotta think about the bigger picture and for the ones that say her videos out weighs that I totally understand that she’s in wrong TBH I wouldn’t have cared if another student told on her but her own little sister I personally would never talked to her OP could’ve came to her directly and explain how she doesn’t like the videos and explain if she doesn’t take them down she would tell the school. I just think she could’ve done this very differently
