There's another set of account credentials here: http://pastebin.com/jHEjBLrQ which are all starting with the letter A. It covers AA to AZ, and spans 900 accounts. Does this mean there's only ~24,000 accounts compromised?
Strangely enough, that was the 'sixth' teaser. I found the fifth -- http://pastebin.com/CsN3SrGA -- but all of the passwords in that list are "latenightbootycalls". I cannot find the 'fourth' just yet.
(Someone let me know if the link to the paste is frowned upon. It's pretty easy to find on Google, however, so I figure I'm doing no additional damage.)
