Article rewriting Vs article spinning

What is the difference between article rewriting Vs article spinning?

1) Traditionally speaking, there is no difference between the two terms. One is just lingo for the other.

2) In a more modern sense, I think there is a trend to consider automated systems that do the “rewriting” for you to be “spinners” versus actual, human “rewriting.”

So, both are the same really, it just means changing words and phrases for similar ones to restructure a piece of text.
