Many of the phantom requests also came from computers masking their IP addresses through anonymous proxy websites overseas, meaning investigators weren't able to trace them and find out who was behind them, let alone their motives. The initial investigation was closed in January without naming any suspects. Cyber law and election experts told NBC that they thought the incident was the first reported case of someone trying to "attack" an online election system in the US, though again, it's worth pointing out that election outcomes weren't impacted and the actual ballots still had to be sent in via snail mail. At the least, the incident is a good reminder of why many election departments in the US are hesitant to embrace fully online voting systems despite the fact that secure online voting is technically feasible.
