When did it become okay to be so mean?

Forgive the bad quality of the photos, I just wanted to show off some outfits that have recently got me slandered in the chat. People keep saying I must’ve farmed for my Runway Diva rank because they don’t like my looks. As someone who hypes up others and tries to be as kind as I can to others, why do people feel the need to bring others down? What do they gain from being cruel?
