Yes - WordAi Version 4 was released!
We removed the Standard Spinner with Version 4. The reason for this is we have now made the Turing Spinner even faster than the old Standard Spinner was. We have also increased the usage limit for the Turing Spinner to 3 million words. So now you can spin more content, it will be higher quality, and it will be faster.
I'll look into this on Monday with our developers and let you know asap - because I agree this is definitely not proper output.
During the launch we limited the size of articles to 2000 words, so you can always break it up into multiple articles. However now that the launch is over and we have made sure that our server cluster can handle current usage we can look into increasing this limit to a larger number (such as 5000 words). If this is a high priority let me know and I can do some stress testing to make sure we can handle articles of that size and see if I can make the change.
