Recently we have received some complaints regarding users failing to credit their sources, failing to obtain permission before using others' work and even stealing credit for other peoples' work. It shouldn't be necessary to caution users on this, however, it is entirely unacceptable to use others' work without permission or claim credit for something you have not produced yourself. An editing community cannot work successfully if people are unhappy to upload their work for fear of it being misused or misrepresented. Do not engage in this behaviour.
