But no one dares to stand up for new users, no one dares to challenge the rules, and novices who are bullied by those guys dare not stand up because their opponents are old users.

That's not true. I've seen people try to change rules, and I've seen rules adjusted because of community requests.

The effort you are putting in these threads you could have put in creating quality posts without plagiarizing

Although this is true, and although technically this topic by itself is ban evasion and thus not allowed, I believe the plagiarism rule sometimes hits the wrong people.
Don't get me wrong: it is plagiarism, and not allowed. But plagiarism (and copyright violations) are all over the internet. When I report plagiarism, I often can't even tell which site has the original, because so many sites have copied the same text.

One more thing I want to say is that unintentional plagiarism, or well-intentioned plagiarism, does not bring any harm to readers. My reason is that plagiarism does not mean cheating

At some point, plagiarism got really out of hand. It was used by bots or workers in sweatshops to maximize signature campaign earnings, followed by text spinners and homograph attacks to make it harder to detect. Thousands of accounts have been banned for this, and they deserve it, but once in a while I stumble upon someone who I think deserves a warning. If that warning arrives before the user is banned, so he can edit his post and improve his behaviour, he can continue being a valuable user.

I think that for novices’ unintentional plagiarism, we can remind or give a warning and let the author indicate the source.

I think you don't realize this isn't deserved in 99% of the plagiarism cases. But there are exceptions, and considering how common plagiarism is on the internet, a Newbie welcome message with a warning would surely help for the few real "accidental" cases.

In OP's case, I think he (she?) can be a contributing user, and I don't think they'll plagiarize again after this warning.
