She has 31 people who gave her money on kofi. If everyone involved was giving 10€ for whatever tip picture there is (which isn't likely), she made a grand total of 310€. That is like 3 dokidoki cosplays on a good day lol.
Most likely she was just sick of people posting AI versions of nudes. Sucks, but has happened to a lot of cosplayers who wear anything remotely skimpy.
