I want to dwell on unintentional plagiarism;
Plagiarism may be said to be unintentional if the plagarist misuses the appropriate method of citation(citing an unexisting or different url from the source). In parentheses is as related to this forum. Or when the plagarist does not know that what he/she copied needs to be cited. Or when the plagarist intention is not to cheat.
There shouldn't be two ways about it, it's either you plagiarized or you didn't. The moment you intentionally copied an article from online, the source should be given credit to, that's how it should be. I don't blame those that come into the forum and plagiarized though, I mean it's becoming a norm thing in the society these days so they might think it doesn't matter here. There's no more morals in the society, people easily steal people works without giving credit to and they go unpunished.
On other social platform, plagiarism isn't been punished as works are been stolen daily without no credits been given and yet there's no punishment to it. e.g on twitter, Facebook etc you can easily copy someone works, post it and get all the credit. Credit has to be given to this forum for still implementing rules that helps keep humanity in check.
The punishment the forum gives for plagiarism help resharp those guilty of it (atleast those that are sorry about what they did and want to change) as it helps them understand that when you steal you'll get punished.
