"Academia has lots and lots and lots of systems in place for assuring that credit is always given where credit is due. If you're writing a paper, there are particular ways to cite internet sources-- even tweets and Facebook posts.
But what about on the internet? We know we're supposed to cite sources, but a standardized system hasn't developed, and in the meantime, you could face a lawsuit if you steal someone else's work, even by accident."
