Article Spinning:
You want an article written for you and spun
> You find someone that can write the article pretty cheap and also spin you about 10 or so for you to use
> There is a high possibility that English is not their first language and very high chance it will not read correctly
> English may be their first language but it probably still won't read well
> They claim that the articles are spun to over 60% per article so Google will not be able to to catch on that they are all the same.
All this for around $10 - Sounds great right
Ok, now let's wake up back into the real world and analyse the above.
You really think that the multi-million dollar Google algorithm is going to be outwitted by someone that has spun 10 articles in 30 mins or less?
You think that the fact that words have been changed, this is what Google looks for?
The Google database algorithm is one of the most complex setups containing algorithms for LSI (Latent Semantic Indexing) as standard. It knows how to recognise spun articles and also how to report back to itself that it has found them.
It also knows the quality of the site on which the spun articles are found. What this means is that if the articles are just re-written articles but on authoritative sites such as newspapers, specific blogs that are tied in/themed with your writings etc, then it will place some more importance on it.
If they are just blasted all over the web via some of those article marketing programs, then be warned as Google have started downgrading a lot of blog-blaster/article sites.
Article Syndication:
This is done by many newspapers/magazines etc and though people think that it can't be any good as it is just the same article syndicated. Again, one needs to bear in mind where it is being syndicated, the authoritativeness of the site syndicating it. If the sites syndicating it have no authority, this is not a major problem as all sites start somewhere and the chances of being punished by Google for this are pretty low.
Best thing to bear in mind is that one pays for what they get and well written articles are not only picked up by non-authoritative sites, but also ones carrying some weight and it is these that will help you the most.
Just to confuse you even more here

I would say that article spinning can work fine but you have to find someone that can do it so that all the articles read well as they quickly proof-read them and don't just hit a spin button and then send them to you. Done by the right person, this will take a while and could cost at least double or triple the $10 one would pay, though well worth it.
Article syndication works just as well and used by many big newspapers or magazines and it doesn't get them into trouble, at worst, Google may just place weight on one of your articles.
