(repost) How to get your IP unbanned on HN

This popped up again today and I'd already forgotten about it, so here is a repost:

HN has a hair trigger about banning IPs that request too fast (sorry about that; we don't have a lot of spare performance), so I wrote something people can use to get their IP unbanned once if it gets banned by accident.

Obviously you have to use it from another IP address, like your phone.

One way in which the ban can be triggered is if you have a lot of browser tabs open on HN and you restart your browser after a crash.
