I haven't poured over the code, but reddit is most definitely more than one server so there's gotta be a sync protocol in there somewhere. So, technically speaking, no restrictions there. Practically speaking, on the other hand, reddit likely never took user content licensing into account to begin with - they never knew they'd get all of digg a couple years in, and 2006 was a different time besides. The only way reddit would be able to release the data now would either be a specific clause (added from the start) allowing such in the TOS, or a general-purpose "we can do w/e we want with your data"; nobody thought to add the former (as noted), and of course the latter would have been roasted alive the moment it was noticed. So, me thinks licensing issues. Modmailing /r/reddit.com is the canonical way to reach the admins (for any reason), if you'd like more info.
