For those of you building PBN's, here's something I came across. In 2013, there was an initiative to perform a census of all the domains in existence. Although they didn't get everything, they amassed a huge collection of domains - over 150 million - all organized by TLD. I've processed a sample of these, and there are definitely some worthwhile expired domains in the bunch. However, since I'm not actively building a PBN, and I'm not a domain reseller, I thought I'd pass along the info. Heres a link to the torrent for the whole dataset: (it's huge, around 12 GB I think, and if you're on Windows, you'll need 7zip to unpack the compressed files) Code: http://1drv.ms/16I1OFL Code: Virus Total: https://www.virustotal.com/en/url/9003550aa1256bc5c87b141e83f8bb35f549f8ccd0f1ab718d72a355ef42dd0b/analysis/1423165418/ Here's a tip if you start processing these - skip the domains at the beginning of the file that start with 0-9. It's almost universally garbage, you'll get better results with domains that start with letters.
