I built millions of ultra-spammy "bad links" into the last remaining website. I did a few other tactics (no hacking and nothing that could even remotely be considered "illegal" was done) and within 2 weeks it (pr5) had dropped off the 1st page.
Google is not going to penalize a website because millions of back-links suddenly appear in two weeks. Google is smart enough to recognize this and simply discount the value that the link may have had.
If this were true, then you would see this happening all over and the search results would be nothing like they are now. I've seen examples of websites claiming to have been penalized only to find the owner of the site did something themselves to cause a penalty and simply couldn't accept responsibility.
The last one I found, the owner cried "Google Penalty" because someone placed almost a 1000 links out on the internet to their site, but what really happened was the owner had made an exact copy of their own website and placed it on another domain. Google found it, selected the new domain as being the legitimate site and removed the other domain (now a copy) from the index.
Link warnings stared on July 20th and were followed by Google's notice that these warnings mean only that the links will be ignored and will not cause any detriment to your site.
Yesterday, we took another step towards more transparency and began sending messages when we distrust some individual links to a site. While itís possible for this to indicate potential spammy activity by the site, it can also have innocent reasons. For example, we may take this kind of targeted action to distrust hacked links pointing to an innocent site. The innocent site will get the message as we move towards more transparency, but itís not necessarily something that you automatically need to worry about.
We made two changes so you can tell the "individual links aren't trusted" messages from the "our opinion of your entire site is affected" messages.
The purpose of the warnings are so that you'll be aware that links you are building are not going to be of any value and/or, are happening too fast.
If you could get a website removed by simply pointing links to it, no one would be using Google.
