Maybe that's because there definitely are some major flaws in Penguin which are causing false positives and undeserved demotions to a lot of sites without any apparent reason.
That's true, but still *something* had to cause my site to be seen as a "false positive". And whatever the problem with that page, the other engines tanked it, too. It's nowhere to be found in any of them. While I totally respect your suggestion to put it back up and "forget Google", if it's toxic in all the engines it probably isn't helping the sites it links out to.
The problem I have with your theory is that it would have taken out a lot more WordPress sites than it did. Like maybe most of them, since trackbacks are enabled by default.
Actually, it would only affect those Wordpress sites that had pages with over 100 links on them. Just going by what I see and what my own sites contain, that's a pretty unusual occurrence.
