>to have police put their blackmailing asses in the jail.
Email is global. You and I are in privileged positions regarding access to capable law enforcement. We're also privileged with what our societies deems acceptable. We are the exception, not the rule.
If you're only thinking about how it affects you and what remedies you would have, then you clearly aren't looking at the big picture.
I'm from Serbia, so no, I'm not really privileged with any of that as we've got oppressive regime in power, inefficient police used to look the other way on crimes, and fairly close-minded and conservative society. Of course, there are places where it's far worse, but I had fairly enough of shit happen to me so far in life (break-up of the country, years of war, living under UN sanctions, hyperinflation, working for $5/month, full-blown dictatorship with secret police killing people, etc.) that I like to think that I actually do have some clue on "a big picture"...
>the solution is [...] to have police put their blackmailing asses in the jail.
But now, you're saying you don't have meaningful access to law enforcement (in this context). So, why did you suggest a solution you know isn't viable? I don't get it.
To my mind, you've just made a strong argument for publishing DKIM keys since you readily admit law enforcement cannot tackle the blackmail problem. Indeed, even in countries with "good" law enforcement, they can't reasonably tackle it since the blackmailers almost always come from overseas (or are un-traceable).
A) Because I'm not focusing on myself here, and realistically majority of people affected by these crimes live in the 1st world countries and will have access to some level of legal protection, and
B) Even though it's not viable for me to do anything to someone in Russia or China or even US for leaking my data, I see that as the only proper way to address this type of situations. If it's not possible now, then we should concentrate on fixing it and making it possible, instead of trying to lessen the impact, but at the same time helping those same blackmailers to easier hide their own steps (and a bunch of other shady characters who'd rather not be linked to their emails, from pedophiles to corrupted politicians). And also I don't see denying as a reasonable move here, as it comes down to basically lying publicly about the origin of your data and can just get you deeper in the trouble, especially if you're in any sensitive position and there're people out there actively looking to dig your dirt. AFAIK all PR handbooks on damage control say the same.
