I'm curious how one-click unsubscribes continue to function, then. Wouldn't those need to be GET requests (due to being a link)?

Take a look. All modern unsubscribes are a get followed by a post for exactly this reason.

Beware, one of the unwritten laws of HN is that any post containing anything vaguely reminiscent of reddit gets downvoted. Upvoted in order to pre-empt the inevitable downvote.

Thanks! I wasn't attempting to bring something reddit-esq to HN, I simply enjoy learning new tidbits everyday on HN!

Would you consider an unsubscribe page that used javascript to automatically make a PUT/POST unsubscribe call on pageload bad practice then?

The google-bots wouldn't affect it since they don't run javascript

Google seems to be running JavaScript for a while now:

They do and they are (at least where I have worked) but it seems that Google et. alia are smart enough to not follow links marked containing text with the value "Unsubscribe".
