Thank you very much for your help, guys! This person deleted my art today))) And at the same time indignant about my rudeness... Hmph, rude for rude. I'm no longer tolerate, that my creation was on the third-party site. I doing it by myself.
Good understanding people always ask me for permission to use or reblogged drawing for the cover of a fanfic... This is nice.
Now I know what to do, that no one else dared to touch my pics - in each art I'll leave watermark and delete share button.
I'd already begun, so that soon all my arts are marked.
