That's not paraphrasing, OP; that's word-substitution plagiarism.
We probably unknowingly paraphrase other people's ideas off the top of our heads when we write here, but most of us aren't looking at someone else's text when we're writing a post--and that's the difference. That text-spinning shit is straight up plagiarism.

a hard-working guy
Yeah, assuming he didn't use a bot to do it. And if he didn't, why not just put that same amount of effort into writing a post with your own thoughts? I don't get it.
