I am definitely with you guys in this initiative. Plagiarism is a slippery slope and it becomes much harder to deal with it, when all voices raised are not being heard.
It is very hard for me to understand, how one can derive pleasure from posting someone else's work as their own? It is not even your own words, it's not something you have a connection with. You have to understand what a writer spills onto paper is in many ways connected to them personally. The two minute fame from someone else's work won't last forever. Your own writing regardless of how it is written, will always mean much more.
Words are capable of so much and especially when they are your own, they become the strongest voice you have. Please, please, write your own stories and do not plagiarize.
