Hi Chris 🙂
There is too much FUD ( fear, uncertainity and doubt ) running wild and crazy nowadays in the SEO realms.
The truth is that the best defense is proactive and preemptive approach – i.e. best of all is to never get in the troubles’ way, never get penalized.
And just in case and if need be – if disaster strikes, then just deal with it and fix it, rather than panic.
“Fear is the path to the dark side”, says Yoda as.
“never get penalized” tell that to the thousands of sites that got hit…hindsight is always good after the fact!
I think many SEO “experts” would love to know what the “proactive and preemptive approach” is?
The proactive and preemtive approach is to never get in the harms way, while riding as fast and as close to its limits 🙂
