Honestly, it's why I urge people not to engage in it. If you dox someone, you've lost your nuclear deterrent. You have nothing left to incentivize them against revenge doxxing or worse.
We've had some users who've been doxxed by cows who went on to be doxxed themselves. Tell me, with everyone's info out in the open, what prevents those users from swatting the cow that doxxed them in retaliation?
I try to be careful to prevent being doxxed, but I'm also confident that should it happen, I can ensure that it's the definition of a Pyrrhic victory.
Edit: Just to be clear, I don't advocate doxxing, swatting, or any of that nasty shit. If you're thinking about doing that, you're a shitty person and shouldn't do that. The point of this post was to illustrate the problem with starting a battle of escalation. There are lines that shouldn't be crossed.
