In this case I'm pretty sure OP knows what he did, I just don't think he knew it was a rule.  I don't think any of these people know plagiarism is banned here.  You look around the internet and it's everywhere, whether it's straight-up copy/pasting or text spinning.  I don't know how many times I've googled something, and the results have all been from different websites yet the content has either been an identical copy or just slightly different, with no note made of copyright or anything like that.

Doesn't surprise me that when folks come here and haven't read the rules, they think it's A-OK to just insert someone else's content into a post here, call it their own, and get paid for it.  I'm sure in some cultures that's completely acceptable, too.
