I've been busy most of the week, but if I'd been here I'd have voted not to lock it, at least at the point it was locked. I don't feel like it needed it. It certainly had the potential to go that way, but I don't think we should be locking threads just because they might at some point need to be locked. I don't believe in preemptive strikes.
Also, this is probably neither the time nor the place, but is there a reason the email telling me somebody reported something for moderation doesn't have the reported post in it? I got UncleBob's report, but I didn't have time to check the forums and wanted to know what he was complaining about.
