TL;DR The new URL is http://kiwifarmsaaf4t2h7gc3dfc5ojhmqruw2nit3uejrpiagrxeuxiyxcyd.onion/.

You can access it in a few ways:

Using a Tor gateway.

Visit https://kiwifarmsaaf4t2h7gc3dfc5ojhmqruw2nit3uejrpiagrxeuxiyxcyd.onion.moe/.

Logging in isn't particularly recommended as it depends on the trust in the gateway's owner.

Using the Tor Browser.

1. Download and install from https://www.torproject.org/download/. It's a modified version of Firefox.
2. Press 'connect' once a new tab opens. You may also choose connecting to Tor automatically.
3. Navigate to http://kiwifarmsaaf4t2h7gc3dfc5ojhmqruw2nit3uejrpiagrxeuxiyxcyd.onion/.
4. You can turn on browser cache, history and password saving. After all, nothing on the site is illegal.
