1script, what do you mean by "automatic" penalties? Or do you mean algorithmic?
Unnatural links penalties are manual, have an expiration date (but can be reapplied at any time), need a cleanup, maybe a link disavow submission and a reconsideration request.
A site that doesn't fit the algorithm will always run afoul until whatever is wrong is fixed, and then maybe not until any special algorithmic bits are rerun.
