Modern media is about inspiring, educating, and entertaining in a positive way. A 'big brother turns brother into slut stories' type of concept is far from what is considered acceptable. There are strict ethical guidelines in media production, and this kind of content would not pass those standards. Instead, we see stories of brothers supporting each other in achieving their dreams, like in some sports - themed movies where brothers train together and build each other up.
Definitely not. The modern media landscape is focused on a wide range of positive topics. Such a concept is not only offensive but also against the values that most media platforms strive to uphold. We see a lot of content about positive family relationships, not this kind of negative and inappropriate transformation.
