Went through the drama on twitter. It felt so much like a high school drama so i didnt take the time to post it here. But since you asked.
This is the thread where she got doxed. Important to note that the dox was not "intentionial" and was deleted after seconds according the the OP.

Damn, she has just locked her account. Doxed girl is correct that a random name popping on twitter doesn't automatically make that name hers, regardless if her first name is known or not. She could have simply deleted the post and say "sorry it seems its posted accidently, I've talked with the person about it" or something instead of going public with the fact that the name belonged to her. So while dox is due to mistake of Hachi, she has confirmed that name is her twice.
Anyway It shouldn't affect anyone else other than those who wanted to commission her.
