I don't think she can win either way now and this could potentially make her worse.
It's a step forward for her (even if she IS spitting the food out) in that she never posts eating videos so she is trying something new and something that would be very, VERY difficult for her to do (again, even if she's spitting it out). On top of that, she has made her fortune from being an anorexic so anything that is the opposite of that risks her income.
When she posts her usual stuff, she gets dozens of comments about how ill she looks, how concerned people are for her, people praying she'll eat etc.
However, the ProAna community is toxic as duck. More so, a lot of the time.
She'll now get comments from that side of the internet talking about how disappointed they are in her, how weak she is, how they thought she was better than that, how that can already see she looks bigger and more filled out. And much worse that that.
Posting an eating video may do the exact opposite of what people want and actually make her more ill because of the bullshit filth she'll get from fellow anorexics.
Time will tell, I guess.
