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.
Some article spinners out there require you to enter your text with properly formatted spintax to create the end result. To create formatted spintax, you'll usually need another tool. But Article Rewriter by Small SEO Tools doesn't require that. Instead, it does all the thinking for you, from taking in the context of every phrase to creating additional textual content that is as readable and meaningful as the text you originally entered.
