I think one of his reasons was that he didn't know it was wrong. He also stated in his introduction post that he is a university student of mathematics. I find it hard to believe a university would allow fraud let alone plagiarism.
A student of mathematics is a very occupied student. Always reading and solving and trying out new methods to tackle an issue, ways burning the night candle. I guess that's it, he probably has no time to sit and create a good content.
I can't really say anything about him but I know that if I'm caught with a plagiarized post, the shame alone would make me rethink my steps.
I don't have time either to create good content all the time. I don't copy/paste articles/comments and try to pass them off as my own.
It's actually a criminal act, it can make you lose everything you worked for on the platform.
And then some. Take, for instance, the Hive member PurePinay. She's got 11K followers. She does well on the platform. She hired ghostwriters to produce content and she never checked them before posting it and that content was plagiarized. There's more to follow on it, but the current results aren't good. Yeah, when something like that happens people are very quick, and justified, to lose trust.
You can get that trust back in some ways. The users searching through months of her posts is one way that it might work. Who is going to do it? The author (no)? The user reading her content (hell no). A most reasonable answer is to just not do it. Easier said than done, I think.
Easier said than done.
On a real note, as a curator, if I were to see a plagarized post over and over again, I'd lose interest and trust.
Rather I'd take my upvotes to people who really deserve them, so I guess you're right.
