If you do not want to write fresh content yourself or you do not have time, I suggest you outsource the job. Make sure whom ever you outsource to is writing them from scratch and not usinga spinner themselves. My favourite are seoarticlewritingpros.com but you can also outsorce companies like www.contentproz.net or www.articlewritingservices.org plus loads of others too.
For many years people used article spinners to mass produce unique content from one source article without really thinking about the quality and the human-friendly flow when it came to a real human having to read the content they landed on when visiting the website. Much more emphasis was put on producing content that was purely made to fool the search engines and rank the website accordingly.
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.
