so i just got a warning and one of my submissions is removed because it says the copyright is owned by ~Lucysnowdowne ...
the submission was this, it's titled "3D graph paper"  
here's something i wanna say to this person:
ok, i admit i DID NOT invent this kind of paper, but as far as i know it's NOT branded by any person or company yet, because this is like some of texture paper you can find in the stationery store. now you've reported and let them removed it successfully, then may ask you to show me your proof that can prove you have the right for doing this?  if not, i may consider you as a liar and i've already contacted to dA to ask for help
