Is this user "tyamosi" really the artist Tsunako, and is that even his//her real e-mail? Sounds like an imposter to me, but if the real artist is here, they should contacted the website owner about it instead.

The email is correct but I don't trust this user either, so I sent a message on his official site to confirm if it was her

Well she answer me very fast

"Hello. I'm Tsunako.

We have several staff members requesting removal for unauthorized reproduction.
In some cases, we may ask another company to remove images or collect usage fees.
So, I'm sorry I don't know which website your report is about.
We are not good at english, so I'm sorry if our way was wrong.

However, I do not allow any unauthorized reproduction of my work.
If you have administrative rights, please delete them all immediately.

Thank you for reading."

I guess it was someone who works with her, so I prefer to respect what she told me and I would like some moderator to delete those scans

Did they mean the one in pool #96930 or every single scan uploaded here? I'm hoping the former and not the later, but that's a whole another can of worms there.

I only asked about this book since she published it recently, I have no idea about the other scans

It has been made clear last time that all the copyright related claims should be dealt by Checkmate directly by sending him email.
