Webmasters still aren’t learning it seems. The forums are still heated up with webmasters with MFA sites bitching about getting deindexed. Google put out warnings and sites that are even ten years old are getting hammered and booted.
One of the main reasons is the lack of focus, trust and integrity of these sites. Adam Lasnik of Google responded in Google Groups that the booting was justified.
Just as I reported earlier with the 10,000 pairs of eyes Google has manually looking at the quality of search results … and you know that quality of sites is being looked at as well.
Play smart and don’t bitch in forums … spend your energy finding the solution. You’ll find it faster that way. 
The main reason I started the SEO Revolution was out of frustration. Frustration at all of the lies and misconceptions that are posted in forums, given as advice in teleconferences, and even taught in live workshops. "So why didn't all of this work?" " Why wasn't my site successful?" " Why am I still stuck in a rut?"
