I read through this thread and definitely agree with a lot of what was said! I definitely think the recent growth in "mental health awareness" (if you could call it that) has also created a huge opening for these types of people to post under those topics to openly boast and engage in validating, attention seeking behaviour while hiding behind a shield of "honesty" or "venting", and if anyone was to react negatively to it, they will throw up the defence of "body/skinny shaming, having prejudice to mental illness, 'this is the reality of mental illness dont like it don't look!!'"
I've seen a huge rise in people posting "day in the life of anorexia recovery" sort of videos, and absolutely not doing anything that really focuses on recovery, just a bunch of boasting restriction, boasting extremely low weights with a few body checks clipped in between. (I swear I have blocked so many accounts and they just do not leave my algorithm, the algorithm really doesn't let go of a topic no matter how many times you try to disengage with it..) I think the recent rise in aesthetics, fitness, "it girl" types of posts also give people more subtle opportunities to post clearly disordered behaviour under a mask that is more "acceptable".
Im not sure if i'm just overly skeptical of others or if it is how I see it, but it really seems like there are many creators who most definitely have eating disorders and love to show it off by posting grwm/fit check videos that are just body checking over and over, not saying that every thin person who posts online is attention seeking or boasting it, just the accounts that clearly engage with that kind of behaviour.
I've also seen a very cringey rise in girls aestheticising being skinny, as posted earlier in the threads, I wish these people would just go find their own communities and spaces that isn't on one of the biggest social media platforms. I can understand wanting to talk about it, get validation or flex ect, but just do it in an appropriate space. We don't need more young girls falling into these illnesses, there's clearly enough of a problem with normal social media usage let alone the weird normalisation of deadly disorders for an "aesthetic".
