I have to make this topic after reading many posts by my fellow newbies about Plagiarism without taking into consideration things that are synonymous to Plagiarism.
Plagiarism and Paraphrasing are different sins of equal magnitude.
Plagiarism is stealing works of the others without any single word, link to mention about the author and original work.
Paraphrase is one of plagiarism types and each university, platform will have their limit of how many percent of words that are taken from the original sources to be considered as plagiarism.
Copy & paste
Paraphrase
Text spinning
You have to leave links to original works.
While the former is the outright lifting of someone's work either in the forum or outside the forum without due reference to the source. The later can be said to be the act of re-writing someone's idea in your own words or understanding in order to enhance clarity.
Paraphrasing might not be called a sin if the source is duly cited.
Many times, the original authors write better because they are at upper class. They have original ideas and have better writing skills. I don't really see demand to paraphrase anything. Quoting the original content is the best.
I don't feel I can clarify it better when I paraphrase, maybe I am a better writer.
Translation without referencing the source can be seen as Paraphrasing in different languages (while paraphrasing is done in same language in either different or same language code).
Translation without referencing the source should also be seen as an advanced Plagiarism.
Mainly they will use Translation tool, engine and not use their brain to translate anything. Because they want to be as knowledgeable as possible even they don't have knowledge and being lazy.
A conclusion. If you don't have your unique opinion and use opinions, contents of others, leave the source link.
