DMOZ Found To Be "Selling" Links?

I was just trying to do the usual thing of registering a new client with the relevant directories. I obviously start with DMOZ (it's a habit thing) but was shocked at what I found.

My client offers mortgages in Cheshire, so I obviously try and find the relevant category. They don't have a county listing which is ok. But then when I try and find the one for the letter "D" I notice that the nice friendly (not so useful) Page Rank Toolbar is showing as blanked out.

I have a look at some other letter categories in the mortgage area and they're all pretty much blank or have 0 PR.

I don't have any history for the Page Rank for DMOZ in this industry but have they been assessed as "selling links"? Wouldn't DMOZ be immune from any assessment as such?

But when I go to my local category there's no PR either!

So I look further! If you start at the root there's an 8, as you go further into the UK's regional listing you get a 7. But as soon as you get into Business & Economy, bamm! it disappears!! Then onto "Personal Finance" - nope, none!

Ahh! But "Art's and Entertainment" is ok, there's PR. "Education" is fine. Even "Shopping" is ok. So what's going on?

Is it just a glitch, or is it something more sinister?? And what implications does this have for the basics of link building?

I think it also goes some way to proving that Google doesn't issue algo changes, or penalties "carte blanche" but does try and understand that processes and practices differ by industry. But I think it also may go some way of proving that that they don't always get it right(?)
