And from that same page, "better for whom?"
It takes great care to attempt to apply knowledge from one domain to another domain. Humans are great at seeing patterns and making analogies, but no matter how many times you say "technology is evolving," that won't make it adhere to the Hardy-Weinberg principle[0]. Attempts to actually implement these analogies tend to be problematic[1].
The US justice system, on the federal and state level, has a wide array of checks against it that (nominally) protect people from state abuse. This is necessary because of the vast power imbalance between a nation-state and a private individual. In this case, it's probably far better to have a 10:1 false negative:false positive ratio. The more false positives, the more potential for abuse.
Conventions and the hacker community do not have the power of nation-states. There's no reason to apply the same very stringent and very necessary restrictions that we apply on nation-states to DefCon. DefCon cannot hurt you the same way the US government can.
So, who is this better for? Certainly not the women attacked: they're left with few options, little sympathy, and copious amounts of victim blaming and denial (as the current top comment indicates). It's far better for the abusers -- especially when the potential for system abuse is far less, because conventions and other hacker/tech events are not nation-states.
If we're going to solve this (or any) problem, we need to look past platitudes and into quantified, measured thought towards a solution. This might very well be naming and shaming likely perpetrators, especially when the evidence is more convincing than a few twitter posts two years ago. We might get more false positives, but we have to contrast this with the current status quo of simply denying any justice to the people actually being harassed for their gender. Personally, I think the cost-benefit is overwhelmingly in favor of excluding more maybe/maybe-not abusive men from our communities, if it results in half the human population being allowed to add their talent to the collective pool.
