Pro-Ana. That is a thing now. It means pro-anorexia. Also a thing: Pro-Mia, meaning pro-bulimia.
TikTok has banned pro-ana and pro-mia accounts because obviously, this is a harmful and dangerous way to live. It also banned the corresponding hashtags, redirecting anyone who searched them to an eating disorder support page. Users have found a way around that by searching just the words without the hashtags. Good grief.
