URL started adding &z=1 in the end

It started happening only recently.
For example :
https://danbooru.donmai.us/posts?tags=xiaoshou_xiansheng
when I click the "Artist" tag on the left, the URL changes to:
https://danbooru.donmai.us/posts?tags=xiaoshou_xiansheng&z=1
or
https://danbooru.donmai.us/posts?tags=xiaoshou_xiansheng&z=2

Is there any way to stop this from happening? it makes managing artist duplicates in my bookmarks a real chore.

I remember the last time this was done

Tracking/telemetry should be opt-out by default.

All telemetry is internally consumed, we don't send data to anyone else. If you don't want your usage of the site to be tracked you shouldn't be using danbooru at all, because anyone with access to the servers can see every single page you visit. This applies to every site.

To add to what NNT said, that back then was an external tracking company, which is why an opt-out made sense.

Explanation

You can use this small userscript:

// ==UserScript==
// @name        Danbooru remove z=N URL param
// @match       *://*.donmai.us/*
// @version     0.1
// @author      Nameless Contributor
// @run-at      document-start
// ==/UserScript==

const params = new URLSearchParams(location.search);
if (params.has('z')) {
  params.delete('z');
  location.search = params.toString();
}

Or add this to your uBlock filters:

||danbooru.donmai.us^$removeparam=z

The first option doesn't interfere with Danbooru getting statistics about clicks but takes marginally longer to load.

uBlock solution worked, Thank you.
