I enjoy the Winter Bash and want to encourage our community to participate. But please participate sanely.
Please stop flagging a bajillion comments. I like comment clean-up as much as the next mod, but the hat is specifically for your own comments. You can delete those yourself, please and thank you.
There is a secret hat for posting a bug on Meta (plus some other conditions). Do not post a fake bug on Meta to get this hat. If you want this hat (and I really do), find a real bug to report.
