nestautobothq do not approve of art thieves or those pretending to be the real artist who did them.
The user Rex-suler is such a person. He pretended to be the real artist of the Transformers artwork done by . He is the real artist of the artwork that Rex-suler is claiming to be his work.

I was informed by 's blog which reveals the truth.

This user pretends to be the official artist Kaworu Kasumi, the author of Transformers Card Game. He uses the artist's personal data (name, age, etc) and art to gain a  fanbase and collect goods. He is also using several puppet accounts for spamming and trolling.

Proof:
The original artist's Deviantart account: ~ and his disclaimer: [link]

Other works created by "His Sister" found on Pixiv: 天照 posted without permission.

NEW INFORMATION: His other DA accounts to which he may try to get his images into your group are as follows: !Amaters ~Jorge-Moreno !Konrito ~HibikiRegister are also his. They are not the real artists accounts.

This deviantart group does not support drama and is not a anti-art-theft organization. The Admin, however, is concerned and thinks that the Members should be informed about this situation, because many people have been cheated by this person (other account: !Rex-tuler) so far. Some people even donated him Premium Membership and the Admin wants to prevent such situation from happening again.

The reposted art has been removed and the user banned from the group. Such behavior is not a typical art theft and will not meet with any forbearance here.

If you have him in your groups please remove his artwork and him as he is not the real artist.
