Ask HN: IP blocked after refreshing too much

Yesterday I submitted a post and wanted to watch its votes/time trajectory as it moved up in the rankings. In order to do that I refreshed fairly frequently and got my IP banned.

Is there a reasonable mechanism to appeal this?

For reference the ip is 69.26.158.178

You should be unbanned in about a day. I had this happen to me (and learned that Ctrl-R in Chrome has little to no delay between sending millions of requests), and was unbanned about a day later.
