PLAGiARiSM and iNFRiNGEMENT
These are rules and guidelines. It is necessary to understand the contents of this post. Please post any questions and comments on this thread.
What is Plagiarism?
Plagiarism is the act of passing off someone else's work and ideas as your own, intentionally or unintentionally. Plagiarism is not a legal issue, but it is a moral one. The wrongness of plagiarism is based on context, intent, and social norms. There are gray areas and this post should help you avoid them.
What is Infringement?
Copyright infringement is the act of copying someone else's work without their permission while the work is still under copyright. Copyright is a legal issue. There are gray areas that fall under "fair use" and "derivative works".
Fair use allows limited copying of a copyrighted work without asking for permission under certain circumstances. Please familiarize yourselves with fair use if you are to work with anything under copyright that is not your own. This post will not go further into fair use.
Plagiarism vs. Copyright
Plagiarism and copyright infringement are not the same thing. It is possible to plagiarize without infringing on someone else's copyright and it is possible to infringe on someone else's copyright without plagiarizing.
Example I:
If you copy Romeo and Juliet without giving credit to Shakespeare, you are plagiarizing. Shakespeare's works are not under copyright, so there is no infringement.
Example II:
If you copy Harry Potter and the Order of the Phoenix and give credit to J.K. Rowling, you are infringing on her copyright if you did not get permission to copy Harry Potter and the Order of the Phoenix. You did not plagiarize as you had stated the work was not your own.
Plagiarism vs. Allusion
The use of allusions can be construed as plagiarism but the difference is in the intent. When intentionally alluding, you hope that someone will notice the similarity to another work. When intentionally plagiarizing, you hope that someone will not notice the similarity to another work.
Avoiding Intentional Plagiarism
There is no avoiding intentional plagiarism except by not doing it. Intentionally stealing someone else's work will earn you a lengthy ban if not a permanent one. It has been said enough times in this thread that plagiarism will not be tolerated and the fact that plagiarism has its own post reiterating some of what has already been said means you're more likely to be permanently banned for intentionally stealing someone else's creative work.
Avoiding Unintentional Plagiarism
The best way to avoid unintentional plagiarism is to credit and source what you did not create, within reason. You cannot plagiarize common knowledge and facts. The more unique or obscure the part you used, the more likely you will have to credit or source it. (Also read "Plagiarism vs. Allusion" above.)
Permissible use
You must follow any stipulations by the original creator if you are allowed to use their work. Read any and all copyrights, conditions, etc. attached to a work before using it. Credit the creator unless they say otherwise.
Fair use
If you are using someone else's character, settings, etc. you must give them credit. Not crediting the original creator may or may not be infringement but it is definitely plagiarism.
Use of other users' works
Using another user's image, work, characters, ideas, settings, etc. without their express permission is not allowed if you do not know that they would be okay with it. Even if your use falls under "fair use" or may not be copyrightable, please respect another users wishes if they do not want you using their creative material.
