Your experience is interesting. Thank you for sharing with us. I also received a notice on March 2, but I have no way of knowing if it was an algorithmic notice or manual action. I have only seen a ranking reduction on one phrase (fell 300 positions, two weeks after the notice), but traffic was largely unaffected. I'm trying decide what to do, but I am inclined to wait it out.
