Out of 250,000 pages scraped i found 66 urls that (what i think) are good. Usually this hard?

Ive had scrapebox for about 2 week now, its very very good and has helped me loads.

I dont bother posting on pages that have loads of spam, the links on those pages probably dont count for anything, im sure google can tell a page that has been spammed to death.

Most do follow pages i find are spammed to death.

After a week of letting scrapebox run through everything i have found 66 pages (33 unique domains) which seem to be good

The links i classify as good have to meet the following criteria

a) Are obviously dofollow
b) Accept comments
c) Have page rank 1+ (at the moment my criteria is low, anything pr1+ is good for me)
d) Have low OBL - Anything 100-200 i will check to see if it has been spammed

Anything 200+ i just delete

So i have 33 unique domains that match this criteria.

Its taken me about 1 week to breakdown the list into these final results

It seems a little low to me?

Does anyone else have better results or is the internet saturated with spam now -_-

Is there any other criteria i should take on board or are there things i can be less strict on - ie if its pr4+ and has 200OBL its still worth a post etc?

Appreciate any help
