I'm very aware of the constant theft of other's artworks and photographs. It's such a shame and i know that sites such as Deviantart are trying their best to control this super sorry plague. It makes me angry at the thought that these people, whether it be adults or children...and you KNOW who you are, hide behind the internet to build a false sense of identity. This is a form of identity theft....even though the correct term is plagary.
Whatever these thieves purpose is for stealing art/photographs/writing:
This message is for you Thieves....
I hope your art project fails,
I hope your parents catch you and spank your immature baby-butt an send you to take real art classes,
I hope your supposed clients find out you are a no good liar,
I hope you are still unliked by other human beings,
I hope you fall flat on your face and break your nose,
I hope no matter what you do in life you feel like a shitty human being,
I hope guilt eats you up inside,
I hope karma really bites you in the butt and it gets really really infected,
and
I hope one day you will learn, become a better person and stop it.

My art is not all that great, and I know its not worth stealing, but if it ever happens....I will find out.
