When I read her Twitter posts, since I didn't hear of her making any mention of a reduction I assumed that the "unfortunate decision" she was referring to no longer posting pics or streaming on Twitch due to real life stalkers. She has stated that she loves her body and wants to keep her breasts, so I doubt she's going to get a reduction - especially since she can get a government funded operation at anytime.
I believe the unfortunate decision she was referring to was no longer being able to post new pics or go on Twitch. Also since she can't find any clothes to fit her, that could also be another reason why she doesn't post anything new. Even before her problems with those stalkers, she said she would not return to Twitch or post new pics until she stopped growing and got a bra that fits. So either way, it appears unlikely we'll ever see anything new from her knowing what we do now. I wish her the best and hope that she find happiness in whatever she decides to do now.
