bad behavior tolerated??

what does it take to get kicked out of these sororities?? i heard abt a theta freshman who posted this january a vid of her pouring vodka into everyones mouths including her own on her public snap story and clearly that wasnt enough to get her dropped. is it just theta that tolerates this behavior? im a rising freshman thinking about rush and everyone is making a big deal about making ur social media all perfect, pls tell me if the rest of the sororities actually care abt this
