If I got banned from an IRC server, switched my proxy settings and came back on to spam a channel with "I Dunno LOL ¯\(°_o)/¯" Can I be prosecuted and sent to prison for it? After all, I'm "evading access restrictions" and every other ridiculous vague threshold for illegal activity Aaron was charged with.
The programmer/lurker in me would react by banning open proxies (DNSBL?) and requiring registration. Which is what we've been doing for decades. Would the federal prosecutor in you hunt down this potentially 10 year old kid and charge them with computer fraud to set an example?
I think the sane reaction to a security issue is to fix the issue. Especially in the cyberlibterarian utopia I wish the Internet was. If it was exploited with enough maliciousness, I can look the other way while the hacker is sentenced for it.
But for something this stupid? An open wifi network? An open closet? Aaron broke through no walls but made-up protocol restrictions. Where is the line drawn?
