i'll upload an article about all those myths around tumblr . i must .
As expert know's the best way to find broken links is tool like "well its better to not say". and much of ram ..
Even with a server machine with 256gb ram i could only download 32% of all tumblr .
Yes i found lot of broken links and removed blogs , and yes a good amount of it was pr6 and above.
But .. most of them are well "in my opinion" already bought by some poeple thought tumblr itself . yes i beilive that .
How many poeple has server machine's with this amount of ram so they can crawl a big site like this ? FEW
and how many from those FEW'S happends to do seo's and etc job's ? fewer than FEW.
So , how its possible from 280 domains with good pr i get only 2? the most of them was taken , or better , pre-taken ... with the title <h1>There's nothing there</h1> still stood.
I found up to 1000 pr 4 and below. i kept some for my own ofcourse . but i could get as much as i wanted at pr6 and above . only one pr6 and thats it.
Someone from the tumblr team is a nasty boy and sell blogs to blackmarket .. this is sure ..
