as for OT, spun articles are essentially dupe "content"
claus... perhaps on a purely mechanical level spun articles can be called "dupe content" ... but don't you think that Google also factors
intent into this, just as they used to? This isn't just accidental duplication. To stretch an analogy, this could be seen as a type of counterfeiting.
Google is very big on intent, and the cynicism behind spun content, particularly badly spun content detected by manual review, would, IMO, add considerably to the gravity of the offense.
All that said, I do agree with observations here that Google has expressed the desire to see good use made of good domains. It's not wanting to create derelicts littering the web... so a large turnaround in a site, useful content with, say, "more mojo", capable of attracting better natural links... along with succinct and relevant reconsideration requests... might constitute the kind of concrete action that Google pays attention to. On the other hand, Google is not wanting to waste time with repeat offenders, and I think content spinning is likely to be a special classification.
I know that Google will want to see evidence of concrete change in content and in tactics, something which will take time. If some of those spun articles get taken down, along with the links from them, that would be helpful. Google won't forget, but they might give the reformed domain a trial pass.
I'll leave the link building tactics for others to discuss... except to say that I believe that Google watches new links to old spammers carefully.
