I never thought that it will happen to me (so soon), but it happened.
A very disgusting person who appears to have no own creativity, has stolen my and Nikoschka's pictures and created a separate account on SheezyArt.com, where she claims to be us. ( [link] and [link] )
On this occasion, I feel obliged to put a watermark on all of my pictures (including future pics).
I'm really very sorry about this, but I do not know how else I can take action against the theft of my images.
