Please don't take this as a spam email because it's not. This entry reminds me of another social network site I know of. It's called Blue Kaffee. If people post copyrighted work or work that isn't their's, there's basically a simple, yet useful report system that this website has. If an administrator catches you stealing other people's work, you're banned. Blue Kaffee even has privacy settings for writings, journals, and galleries, such as friends only, and private.
Plagiarism ia not a big issue on BK, but the mods are quick to respond.
