A federal judge on Thursday ordered Twitter to give up information about three account holders under investigation for possible connections to WikiLeaks. The decision rejected an appeal by the three account holders that argued their IP addresses should be considered private.

Those account holders — Jacob Appelbaum, Rop Gonggrijp and Birgitta Jonsdottir — have addressed the situation on Twitter. Gonggrijp, a Dutch citizen, used his feed to direct users to a blog post arguing that the decision is a blow to Internet privacy.

“The consequences of this decision for me are extremely limited: there’s not a whole lot you can learn from records that Twitter has on me that you can’t learn from reading my blog,” he wrote. “There are bigger principles at stake though, and this is not a good ruling for online privacy.”MORE
