I am a rather gray-hat affiliate marketer by trade, but I"m looking more into going into local SEO and blogging ventures that I feel will be most sustainable. I am having serious moral issues with using any of my link building strategies, but the one I'm struggling morally and long-term strategy-wise is the use of a manufactured link-juice-flowing-thick private blog network. I believe the majority of these will ultimately fall by the wayside in the future when their social value and content are proven to lack substance by machine reading and advanced social metrics. 
Since high quality expired domains are in low supply, the huge numbers of marketers competing for those drop domains tend to drive prices up. Also, if you use an exchange, you’re basically lucky to get whatever you can afford. In other words, niche specificity isn't guaranteed. This is going to be a problem because as Google continues to evolve, it is cracking down on domain niche relevance. In other words, its software is fast evolving to the point that it can tell what the niche of a particular domain is. If your private blog network is a patchwork of expired domains that involve many different and dissimilar niches, then you might be in trouble. You are at great risk of being penalized by Google.
When searching from keyword DHG will take your list of keywords and search each one, the pages will then be crawled to find unique domains to check availability of. The process is relatively simple but very time consuming when done manually or semi automated as was necessary in the past. Luckily now the job can be set and left to work while you do something else.

We just need to take the Archive.org url and plug it into the Dom Recovery software and again, if you just hit recover, paste in the snapshot, click next, next, finish, and I’m going to let this one run in real time for you so you can see just how quick it is, and right now it is downloading the initial page, and now it’s downloading all of the other pages.
The way this list is implemented means I can't update prices, nor removed sold domains automatically and sedo doesn't provide me with the tools I need to implement it properly. Unfortunately some users keep contacting me to update their domain prices or remove their domains and I can't keep doing that manually. So I've decided to disable the list for now.
