I think two of the main things to look for are:
#1 links coming from different IP's (100 links from free hosted blogspot sites on the same 1-3 ip's end up being mostly worthless especially when compared to 100 links from 70 different ip's). Not saying blogspot and similar links are actually worthless, but if you are trading, or paying top dollar your time or money could be better spent.
and
#2 the amount of backlinks on the site linking to you, link juice is distributed over all of the links on the page and you will get far more value/link juice from a site with 0 to 60 OBL than one with 150-300 (i.e.: link farms). Many SEO authorities say try to keep under 50 (or even 30), but with porn sites that is practically impossible to find.. but the lower the better.
I just recently read that even though google does not pass any love to nofollow links it still includes them when divides the juice. In the past I thought it would not count nofollow's to affiliate links and other nofollow links towards the juice passed, but it does.
A ton of people still focus on PR, but from everything I have read, PR is way over-rated and in many circumstances you could get more juice from a pr0 or p1 site than a pr5 in some cases. Some people only get PR5 links, which to google would probably be caught as unnatural to their algorithms. In the real world you cannot control who links to you so odds are there would be a wide variety or pr's and ip's if it were natural.
(Also, I’ll state the obvious, make sure the sites you are getting links from are actually even listed in Google... lol )

You could do that if they were on different class c's and you did only 1 way links, but "link building" pretty much covers gaining one way inbound links in general... ABC trades, forum posts, blog posts, purchasing links, directory listings, etc.. etc..
Most people focus on doing ABC trades or purchasing links so they can dedicate more time to the their main websites. For alot of people the time it would take to make and maintain 100+ sites on different ip's could be better spent working on their main sites adding content, etc.
