Why is this site PR6? Is this a 301 hijack?

Here's an expired "on hold" domain...

http://jennydiet.com/ is PR6
http://www.jennydiet.com/ is PR0

If you do a google...

link:http://jennydiet.com/ you'll see backlinks for jennycraig.com, and NOT jennydiet.com

In fact, link:http://www.jennycraig.com/ shows the exact same number of backlinks, and the same backlinks!

Is this a glitch, or a 301 hijack or ????

 

i strongly suggest you to redirect jennydiet.com/ to www.jennydiet.com/ . this is googles suggest , not mine

 

This looks like a 301 redirect fake.

 

for me both are GrayBared

 

What exactly is the 301 highjack? Like I've heard about but never understood what people meant? It doesn't make sense that when you redirect a page, the page gets the PR or whatever.

 

I don't know how it is done, but a 301 hijack can "steal" the rankings of another site... is that correct? Some of you pro's help me out here.

I got excited and grabbed this domain at TNDAM... guess I'd better let it go as soon as it settles into my account.

Thanks, guys!

 

How it's done is people get a list of IP's that Google Crawlers use and then add a PHP 'IF' tag at the top of their pages seeing the thing viewing the page is a Google Bot, if so, then redirect to a PR10~ site, otherwise if the visitor ISN'T a google bot, then naturally show the site.
