The Electronic Frontier Foundation is running a story about the ongoing Wikileaks investigation:https://www.eff.org/press/releases/privacy-loses-twitterwikileaks-records-battle
Apparently, the courts have ruled that private Twitter records related the case are fair game for inspectors. Users who may have had other information disclosed can’t even find out where the information was disclosed from. Now, Twitter is not to blame for the release of this information and they are keeping users up to date on any information they are forced to reveal, but this should be a wake up call for anyone still snoozing out there.
There is no guarantee that your data is safe once you have uploaded it to a third party. Even information on a service such as Twitter can be used against you. The only real defense is to not post information that may come back to bite you.
