So I had a site that I used to 301 SAPE links to another site, and it got trashed. All links to the site were removed and I applied for reconsideration. It took three tries to get them to remove the unnatural links penalty - and they immediately slapped me with a thin affiliate penalty. The site isn't the most robust I've ever built, but it isn't thin by any stretch of the imagination, either. I'm now just about convinced they won't let you revive a site once they trash it.
