I think she is high or drunk tweeting and deleting when sober. She comes accross as fey during her tweets.
Regarding whether she has intended to deliberately scam, I think she has in many cases. She is calculating and always follows the money. Seeks out rich partners. Monetised a kitten's memorial video, monetised the BLM video, scammed people into paying her to send her own book to a food bank for the full price when she got her books cheap and we don't know if she ever donated. The kickstarter, I suspect she intended to cream something off the top not knowing how much would be donated. Sue Lee, broken website needing funds, woe is me posts leading to funds, HH2, tge Nigella tweets, the Sarah Everard tweets, even blogged about her grandfather's srtious decline in health and lord knows how much more. She has no tact or shame, particularly atound sensitive subjects. She knew what she was doing when she wrote emotionally manipulative tracts about her personal tragedies. She knew gullible, kind people would donate. What is worse is that she knew people who are poor or previously poor would resonate with her experiences and feel compelled to donate when money was tight. She is cruel and greedy and she knows exactly what she is doing. However, I don't think she sat down 10 years ago and mapped out a master grift. I think she wings it and has ideas or grabs opportunities along the way.
