There are certain topics that seem to get instantly flag-killed unusually often. IPv6 is one.
I've been more disturbed by comments that were flagkilled just for being wrongthink, not because they were rude or not well argued. I've also seen a lot less of those flagkills over the last 6 months, which makes me feel like there were some fake accounts that got caught and culled.
I've seen a lot of ipv6 wars here without flagkilling happening
