So you are still doing it? I have stopped using spin content after panda update way couple of years ago. As content become king and the user expereince the key to earn website authority, I started focusing on writing more meaningful and engaging content. I never cam across any spinner that time which makes total sense after spinning. The spin content either looked very bad or it needed manual review. I forgot the name of the spinner tool as well. Looking forward for replied from more experts here as it could be an eye opener for me if spinning still works.
Not sure about version 1, but I'm testing version 2 right now and I have to say it's the best auto spinner I've seen bar none. The content is actually extremely readable and probably better than the manual spins a lot of people do out there. However, some of the content doesn't pass copyscape so make sure you play around with the settings. Minor edits should do the trick. I'm on the trial now but seriously thinking of keeping the Turing plan for my Tier 1 content.
Seriously, if you have a blog or a collection of web 2.0 properties, you want to build some authpority to your additional tier 2 and 3 sites, you want backilinks and endless content for any purpose, then this tool is for you. No matter what business you are in, you are going to need content of some degree and spin rewriter 9 is the perfect solution with out any doubt.
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.
