What happened to the torrents previously hosted by Demonoid? Couldn't magnet links still locate the torrents without the tracker?

edit: The answer as I understand it requires knowledge of the following:

There is an element to a torrent that is called the ‘private flag’. It’s a small flag that marks to a client that the torrent is ‘private’ and disables any method of sharing peers (including DHT), except via the tracker. This flag also changes the hash, so peers on a non-flagged torrent could not connect to a flagged torrent in any case. Most private torrent sites check for the flag, and add it if missing when the torrent is initially uploaded to their site. source

As a private tracker, Demonoid had the private flag enabled so that it could track its users' activity stats. By design, it is impossible to download those torrents without the Demonoid tracker being available. Disabling the private flag from the magnet links would effectively change the torrent, and no peers would be available to download from.

Why do we all get Demonoid's torrents together in a torrent and torrent that shit?

You can search DHT indexing sites for demonoid.txt.

Bitsnoop

Btdigg

Torrentz

Kat

Just add what your looking for to the search. For more specific results use quotes.

No, cause the dht bit that is set on demonoid's torrents files stops that.

They shoulda enable that when they knew they were going down...

u/dizzy1 avatar

That wouldn't have helped. It would only have helped if everyone had then gone and redownloaded all their running torrents from demonoid.

The private setting (which disallows DHT, among other things) is in the info dictionary part of the .torrent file. By changing the flag, you change the contents of the dictionary, and subsequently also change the info hash.

This info hash is the unique identifier for the torrent. Unless everyone else ends up with the now non-private, modified .torrent file, you won't be connecting to peers.

You can also use a hacked client that ignores that flag and uses DHT regardless.

u/Rolcol avatar

That still severely restricts the amount of peers you'll be able to connect to. They'd all need a modified client.

u/jurassic_pork avatar

Indeed. Simply stating that it is a possible if unlikely option.

Torrents from ThePirateBay are trackerless. So if TPB every actually went down, then the torrents would indeed continue to function just fine. There are even some mirror sites which mirror all the magnet links in case the pirate bay goes down.

Those are proxies. They just redirect straight to the pirate bay through a third party, so your ISP can't block the traffic.

A mirror is literally a duplicated website with all the same links and everything, but on a totally different domain and server.

u/LeadStark avatar

Unless its a cache proxy. Like CoralCDN.

is it worth the risk though, feds?
