I don't understand why he plagiarized. Is this the farmer's bounty account?
Likely because he knew he needed one merit to rank up and thus had to make a very good post to get it. Not being very proficient in English, he decided to take the path that many new members take and just copy/paste something useful from the internet and claim it as their own.
That's my guess, but it doesn't really matter. He's not the first to do it and certainly won't be the last, and this is also a good example of why giving merits to Newbies is so difficult. You have to check to see if what looks to be a decent post is plagiarized, because only rarely does this forum attract new members proficient in English.
Most new members come here to make money and can only do so in the main sections where they're forced to write in a language that frankly they're not typically very good at. It wouldn't be a problem if bounties and sig campaigns paid for posts in the local boards, but alas that's usually not the case.
