We have wikileaks etc, but nothing to make it easy for digital preservation of things like this.
Perhaps for games a site like abandonia.com could setup a git server?
I bet there are a ton of people reading this page who have access to old code that if they deleted it, it would be gone forever.
- Share via multiple of the many infamous "file sharing" sites - but pay close attention to the file size limits for free/anonymous downloads
- A torrent, seeded via VPS (as another user suggested). I haven't heard of people using UrDN for this specifically but I think that could be interesting.
- Share via DC++, use the chat system to tell everyone about the TTH at least 5 times within 2 days. (You could run a VPN between said VPS and your PC or use Xvnc/RDP and run DC++ directly from the VPS.)
- Find the underground community most closely related to the source code in question, or just general hacking forums, and share the link(s) there
- Carefully maintain your seed(s) (replacing dead links with new ones, etc) until the link(s) go solidly viral, then to be sure wait the same amount of time again. By this point you should have reached minimal saturation.
- Include SHA256sums of all the files on the website(s) you link to. Make a lot of noise about the checksums, particularly the checksum of the main archive (eg .7z) file. This will help minimize the number of people who try to latch onto/jump on top of your release and claim it as their own - they'll want to include their own message, which would alter the checksum. This is mainly for security, not vanity.
- If you ever think you want to provide updates, write a short message that describes yourself as the original source of this information, SHA512sum that string, and include the checksum in the release. You can then prove your authenticity by including the short message in the update; anybody can verify the SHA512.
- If you want to appeal to the warez scene or you think appealing to that demographic will help spread this, use the .rar format. It's not technically competitive anymore but scene groups traditionally continue to use it.
It should end up in enough caches to be self-replicating after an hour or 2.
