I don't recommend blasting your websites with tons of low quality backlinks. This was just a test - I don't care about that particular website one bit. I always test stuff, like dozens of tests running all the time. I know that correlation doesn't imply causation, you don't need to remind me of that.
One of my mini-niche-sites got hit by Penguin 1.0, lol. So I decided to build about 3000 low quality backlinks to it, using around 300 different anchors (as well as naked URL links, such as site.com).
After a few weeks:
And here's what GWT shows me (there's about 20-30 quality links in there, if that):
Now, will it get nuked again the next Penguin refresh? I doubt it (but that's only an opinion).
Would I use this strategy on my new websites? No.
Once again - this probably isn't a good long-term strategy (but no one can prove or disprove this point tbh). However, there are so many random theories thrown around right now... Do your own testing, because most people don't know ****.
