Thanks! More interested in the scraper.. is it open-source? If yes, where can we download it? If not, can you write about your experience in building it?
Writing a Twitter scraper is pretty trivial and you can find several good examples on Github. I'd put mine online, but the commands I was using in 2009/2010 are changed/deprecated largely and my code wouldn't run.
In either case, as Sethish said, distributing dumps like this is against the new ToS.
