I have generated roughly 50 GB worth of CSA_B8hx030000h chains thus far, which I'm in the process of posting to Usenet. Just search for the header CSA_B8hx030000h_10000h using any newsgroup search engine and you'll find them right away.
Each file is protected with a unique password. I will provide the password to extract one of my chains in exchange for one of your CSA_B8hx030000h chains, and so forth... For example, if you can provide 10 chain files, I will give you the passwords for 10 of my files.
Please PM me if you're interested.
