Portions of Twitter's source code recently appeared on GitHub, and Twitter is trying to force GitHub to identify the user or users who posted the code.

GitHub disabled the repository on Friday shortly after Twitter filed a DMCA (Digital Millennium Copyright Act) takedown notice but apparently hasn't provided the information Twitter is seeking. Twitter's DMCA takedown notice asked GitHub to provide the code submitter's "upload/download/access history," contact information, IP addresses, and any session information or "associated logs related to this repo or any forks."
