I didn't realize this is such an issue.
You know, a couple of days ago when we had this ability to change names, I went out of my way to send Jizz a message informing him of the situation and requesting him to stay on the site. We talked for a while, I told him about how awesome a user he was and how much he'd be missed, and also about how the username isn't the important thing here (the posts and the user in question are). He agreed to stay on the site an extra week while we ironed things out and so additional time could be spent so no rash decisions would be made.
The long and short it is that we don't want him to leave. We wouldn't have messaged him and tried to talk things over if we didn't, because he's a great user. I think people need to realize that we aren't trying to drive anyone off the site; quite the opposite. I think you guys are forgetting that the user himself will be staying, with a name of his choice that is deemed SFW; we definitely aren't going to permaban him over it.
Hopefully that will be the case and he will stay.
