Anybody may do that, all you will need is the ability to chain a sentence jointly and a computer. You're able to compose original articles and distribute them to post submission sites and get paid. You will need to apply to these sites and might or might not get rejected. Should you happen to get rejected then just keep plugging away till you find some body to "hire" you.
Only standard WordAI spinner showed 12% match for me in Copyscape which is very good I think. Also I will add that for SPAM links in general you don’t need any quality at all. if Google crawler can’t find connection with other spinned articles – goal achieved. Sorry, but I don’t see that with expensive spinners as Copyspace shows that in plain sight.
Imo it is not possible for google to detect properly spun content, it is not worth computing power it requires. They can do this using ngrams for example, but it is uses a lot of queries. And for example article spinner I coded beats this algo, so google cant detect that the content is spun. Manual spinning is also good but it takes more than 30 minutes per article.
