Just reading this list I'm sure it would be fairly clear that word
analysis could be used to identify posters. Reread a few posts on the
cypherpunks list. Note who spells out "government" and who abbreviates
to "gov't". Some people consistently use one or the other. Count who
uses "though" and who uses "tho". Also look at who refers to "anonymous
posters" and who talks about "nyms". I think you will notice some
definent patterns. Other possible word favoritisms:
cypherpunks/c-punks
cryptography/crypto
cipher/encryption
America/USA
England/UK
baud/bps
DigiCash/digital cash
Internet/"the net"
information/info
Mail/E-mail/Net-mail
Just looking at the above list I'm sure some of you will realize how
much you favor using certain terms, others probably without noticing it.
Sorting by subject is possible too. Notice that there is only a
certain group of users who consistently discuss DCnets. Another group
consistently mentions the IRS, and taxes. A different group typically
discusses anonymnity and anonymous postings. Others tend to avoid
certain topics. Think about your own postings and realize what topics
interest you most.
I don't think it would be too hard to establish a "text fingerprint" of
people based on what words they use. Maybe when I have some time I'll
write a program to do it and see how many different patterns/styles I
can identify.
P.S. Also note the variations in text markings to express emphasis.
Note who CAPITALIZES, *stars* _underscores_ or Capitalizes The First
Letters.

Though I agree with some other contributors that iron-clad
identification may require substantial amounts of material, I think
Mr. Ghio's point is correct to the extent that a party can satisfy
itself informally that a particular anonymous post is from some
well-known identity. Though the evidence may be useless in a legal
sense, that's not a problem in some contexts.
For example, if Bob Scum is posting anonymously some risky notes to
a particular mailing list or newsgroup, it may be quite unfortunate
for Bob if mere suspicion arises that the notes are from him. That
suspicion need not be based on admissable-in-court evidence; if it's
noted by someone that both Bob and the anonymous author routinely use
the word "copacetic", things could heat up for poor Bob. If the risky
notes involve some socially unacceptable topics like drug use or
pornography, the fact that Bob can't actually be convicted is
unimportant.
