Let me make a hypothetical scenario. Someone asks you to write a satirical post about a topic. While writing it, you look online to see if there are similar posts and find one. You decide that it would be a great idea for this post to expand on the previous post that was written years and years prior. You make the content 100% unique, making it a follow-up segment of the previous post, adding all new and original content aside from the name and base of the story. Plagiarism checkers say it’s fine, and you wrote new content that makes this original and fascinating. It’s also not uncommon and is labeled as Fair Use under the US Copyright Act under Parody,
Sooo… did you do something wrong? Because I don’t see anything wrong with this, and neither do any of my freelance friends.
