Do you just moderate stuff that happens on the discord, or do you ban people if they do some "wrong" stuff outside of discord? Because the CoC draft allows excluding people for doing "wrong" stuff even outside of GCC (-trackers, -mailing lists, etc.).
There's a difference for baning people in places where they should behave professionally, and banning people for stuff they do outside of those places.
It depends, I think, on whether those people represent and reflect on the GCC organization; does the project want to be associated with morally objectionable people?
With other environments like forums, or even single commits or issues opened, I think it shouldn't apply; they're just randos, often even anonymous.
But with some projects, where for legal reasons people's real names & identities have to be exposed, it becomes another matter.
For what it's worth, I dislike real identities on the internet; I think e.g. open source projects should allow contributions from randoms / nicknames. But I guess there's legal issues.
The reason that clause is there is to deal with dedicated harassers who will try to skirt the rules while still attacking their victims.
For example: is hurling abuse at another member about their sexuality in a bar not connected to a conference, "a space under GCC control"?
Technically: no. But those people are only proximal due to participation in the project.
But maybe they don't do it to members. Maybe it's just their hobby - attend GCC conferences and hurl abuse at people in the nearby gay bars each night, then show up the next day in the T-shirt and conference badge, forcing the reception staff they were yelling at the previous night to interact with them.
Again: technically, not connected to GCC. After all - they could fly to any city they want at any time and do this. They're not doing it in "spaces under GCC control". But they're doing it right next to them. And any member of the public making casual observations would start to see the pattern of this happening whenever a GCC conference is in town.
