This is not difficult at all, it just costs bandwidth. The basic idea
is to anonymously post or mail a message, and at the end attach a
public key, and the name of a public forum such as a usenet newsgroup.
Then whoever wants to reply, will encrypt the message with the public
key, and posts to the appropriate newsgroup. No-one but the poster of
the original message can decrypt the reply. since everyone receives
all the articles in the newsgroup, it is not possible to trace back who
decrypted the message.

I would NOT rely on this under any conditions. This could only provide
enough security that someone who is NOT interested in you can not trace you.
Hey, for that kind of security you could use something like rot13...
Anyone that is in the least interested, will immediately investigate the
recent traffic at nodes the message went through.

What I described above can work indefinitely (at least until your private
key is compromised)

Again, I would not use this approach. Such a node would become the target of
concentrated penetration efforts and would break down sooner or later, and
probably would remain operational, while logging all data.
