I don't think she'll just come back tomorrow with her usual drivel, she'd get torn apart. She's left it too long and there's too many comments on her page now to just sweep everything under the carpet.
The best thing for her to do would be to write a heartfelt apology on her grid, and an accompanying blog post, along with everything she's learnt. I'm not sure she will though, she might just disappear. I honestly think that would be better for her in the long run. She had a few good years, absolutely lost the passion, now move on and spend time with your family/get a job.
I do think it's a bit shady how other influencers seem to delight in bringing one of their own down. I'm not defending Hannah at all, but I can't imagine for one second that the others have a perfect track record. Someone said earlier on that it feels a bit like if they can be vocal about another influencers behaviour, they can feel part of the movement, and that really seems to sing true. I don't follow Zoe London but has she always been a pioneer for BLM? I doubt it.
