Hi everyone. So, a little bird told me that this site (and this person) is stealing my work (and other’s work) and putting their copyright on them. Please, someone help me and tell me what to do. apparently the people on this site are just translating them, but still, they are not putting the sources links to the original works.

Every artwork has my mark on it. This person is being highly disrespectful.
Other arts like kelgrid's are being stolen, and marks are being put on them. 
Please, help me report them.
