So I've spent 6-7 hours scraping the web to find some expired domains with good backlink profiles. I've noticed a trend where I'll come across an expired unspammed domain that'll maybe have a total of 5 backlinks, but 2-3 D0 Follow PR 5 backlinks from high authority sites. Do you guys normally pass these over for sites with a more diverse profile or do you think these are worth investing in? I know how wildly inaccurate toolbar PR is, but I've heard that depending on the nature of the PR 5 a single PR 5 link could boost another to a similar page rank. Also I've noticed a lot of sites that were once legitimate, picked up for a foreign blog network, and have now been dropped but they still maintain a legitimate link profile (multiple PR 5's on authority sites) as the blog network owner did not add any additional spammy links to the profile. Strangely, whois doesn't show any drops. I dug a little deeper and also found that the sites the blog network linked out to are still indexed so I don't think the network was deindexed. Many of them have similar stats to the other sites I'm coming across less than 10 total links from unique domains. Should I take it as a red flag and run that they were picked up by a foreign network or do you think they carry any value still?
