Dear Emiko,
Let me help you realize how this world of DA works.
People will know if you are stealing art, for more then half of the pictures you have posted on here are most likely a popular artist.
Also unless you steal from one artist alone their styles vary therfore it can be noticed that they are not yours.
People can report you and tell the original artist about what you have done. Blocking Won't stop someone from seeing your page, they just can't comment or note you, thats it.
and when a certain amount of blocked messages are reached, it alerts DA officials and they will see whats going on in your page.
Emiko, these are not yours, I checked for the original artists and they have been notified, and so has DA.
Take them down or they will Ban your IP from ever beign able to have an account Again.
