I would rather suggest him to wait for a response. If he is really willing to do something for his native speakers, he should not spoil it by breaking a rule and getting a negative impact for that. Patience mostly works better than doing things in hurry.
Hilarious stated this outright that people will get leniancy if they are more notable on the forum. Usually people get banned for plagiarism if there is strong evidence that they have done it multiple times. I don't think a sole plagiarist (that hasnt broken any other rules) has beem nuked (as far as I can tell at least)...
