Anyone submitted google penguin feedback form?

I've heard some experts say that they are very unlikely to change your site's status from this form submission. I am not sure anyone really knows but I think they probably just put it out there to make it appear as if they give a damn!

My site went from $1000/month to zero. I am confident it will make zero over the next 3 weeks because I am on page 33 now (was on page one).

I went over my site with a fine tooth comb yesterday to see if it had "too many keywords" or would be considered spam in any way but, no, it's content rich and a great informative site. I've had others look at it and tell me that content-wise it's great (design wise kind of outdated but I don't mind that, I'm not selling a sexy product and many of my visitors are older).

The SEO experts swear this update is a FILTER, not like Panda, and that it is set to filter only things like too many keywords and other spammy on-site SEO. This is what I would like to know: WHAT is Penguin filtering, exactly, that my site got caught up in its filter? If anyone has any ideas please let me know here or via PM.

I also read saw a youtube video of an SEO expert who says that there were 2 changes:

One was on the 19th and was I believe a Panda 3.5(?) update that had to do with backlinking schemes again

And the other was of course the Penguin filter on the 24th.

So if you look at your site's stats and you see a big drop off around the 22nd - 3 days after the update on the 19th - then you were hit by Panda and you probably have too many dicey backlinks. But if you were hit on the 24th or 25th you were hit by the Penguin FILTER which goes into effect immediately, not after a few days like with the Panda updates.

So I looked at my site and my traffic went from 70-90 per day the week before the 24th, to 10 visitors on the 25th, to 2-3 visitors now that my page was de-ranked to page 30.

This is what I cannot understand because my site is NOT spammy, it's well written by an expert writer on the subject at hand (me). But I did have some dicey links via a WSO article network link scheme. So I can't understand why it appears I was NOT hit by Panda but rather was hit exactly on the 24th by Penguin which is supposed to NOT be related to links.

Anyway, I would not submit my site to Google unless I heard that a large majority of people were getting good results with that. So I thank you for this thread, maybe it will reveal results - good and bad.

I hope that:

A) Google loses the suit that's been filed against them over this; it's actually an FTC complaint as I understand it (I doubt they'll lose though.)
B) Google gets a very bad reputation from this (This is already happening and I'm sure their marketing team is going crazy right now!)
C) Google loses searches to Yahoo, Bing and DuckDuckGo, Dogpile, etc. (I've already stopped using Google except to check my rankings.)

I leave you with this portrait of Matt Cutts, Google's "distinguished engineer":



You've probably seen this by now, but here's a funny youtube about the Penguin filter update in case someone hasn't seen it:
