What qualifies as plagiarism on the forum?
Copying someone else’s work and passing it off as your own.
What are the consequences for violating the plagiarism rule?
If you’re caught plagiarizing, your account will be permanently banned and you cannot create a new one, that would be ban evasion. The only chance you have of coming back to the forum is creating an appeal thread to plead your case.
How can users ensure that their posts are original and do not violate the plagiarism rule?
Try and be as authentic as possible, and add reference links where necessary.
Are there any exceptions or nuances to the plagiarism rule that users should be aware of?
Plagiarism is handled case-by-case, moderators can be lenient sometimes and only delete the plagiarized post instead of banning the account.
