Thus, if you are able to "fix" your backlink profile to make it less prone to Penguin, you are just confirming that you are a dirty spammer in the first place. Spammers don't get rehabilitated.
I hope that that's not the case with Penguin. In my case a 3rd party created lots of empty forum profiles, all with the same user name, all with 0 posts. It was not authorised by me - they were supposed to be publicising a competition but to fill their time ran xrumer or something like it. I was able to get most of it removed. I also removed links from within my own sites (all on topic but nonetheless in my control).
I am hoping that it's a penalty pure and simple and that it will eventually get removed. Whether it will or not remains to be seen.
I do wonder if it was a data mining excercise by google to find out who had access to what.
