This article is from the Dissociation FAQ, by Discord (email@example.com) with numerous contributions by others.
Because of the sensitive nature of the topics to be discussed here, some
people may not feel comfortable unless they have a way to post anonymously.
With the closing of penet.fi, however, the only suggestions I can offer
are the following.
Firstly, Fuzzy -- a long-time regular from ASAR -- runs asarian.org,
where you can get accounts under a pseudonym. While mail sent to those
accounts is in the clear -- i.e., it does NOT anonymize sender the way
penet did -- it does protect the account holder. e-mail
firstname.lastname@example.org for information on how to get an account.
Secondly, there is twwells, information for which is posted periodically
by the person who runs the service. I personally have severe problems
with that service's reputation, but it's up to each of you whether or not
you feel it's justified, and I'm not going to go into my reasons here.
I include the information because it IS an option, despite not being one
I personally recommend.
Lastly, there are a number of remailers, which do not allow anonymous
e-mail, but will allow anonymous posting. I don't have information on
exactly how to go about using them, and the list of which ones are
actually available changes regularly, so my suggestion is that you read
through alt.privacy.anon-server and keep current that way.
