Take a very close look at that image of yours please. You see that little tiny * next to the "Bandwidth: Unlimited*"
It means "Psst! Hey! It's not really unlimited, it's only more bandwidth than a single person could generate!" And I'm sure PC eats about a TB a day at least in images alone! No chance it could survive or thrive on such a limit.
Also, you're concerned about PC's rank? Pff. Alexa can kiss my ass. It doesn't matter. PC is as successful as any administrator here could ever expect it to be, and more. We don't need dirty, low down tricks like SEO to bump PC up in ranks. It's outstanding alone.
I don't condone excessive SEO, and I definitely don't condone VISIBLE SEO. Page load times at PC vary wildly from 1-10 seconds because of the sheer number of members here. If you'd like to see better performance I'm sure the admins would appreciate it more if you simply organized a donation drive or something like that. XD
