“DEF CON never told us what he did to violate the CoC”
DEF CON literally has 1 fucking rule. Don’t harass people. So why do you feel entitled to more information? What exactly do you need?
How many victims? The nature of the harassment? Names?
It’s literally 1 rule
When your local conference then says "Yeah, sure let's have this dude be a 'surprise' guest. And also, sure. Let's have him rant about 'cancel culture'. and not vet a fucking thing he's gonna be talking about to a more or less captive audience is... really tonedeaf.
For them to say "yeah, this dude is a liability and permanently band them" should be seen as the equivalent of taking out the trash.
It's admirable to be the one who says "This shit stops here. We're not gonna enable you."
Oi. I'm only going to say this once. I don't particularly like the Defcon organizers. But generally speaking, when they ban someone from an event, they don't fucking miss.
Considering it's a conference that has a pretty wide spectrum of people...
It's not drama to hold your community to a higher standard and make sure its safe for everyone who is interested. Be better than that.
