It is not immune to spam
Fixable with authentication.
As each individual news article is piped through a relatively small
number of servers in the "core" of the distribution system, it becomes
relatively easy to blacklist known offenders. That is, if they are
recognizable as such. This is where the authentication comes in. The
tricky part is optimizing the time/difficulty it takes to blacklist vs
that of obtaining a new identity.
Also note that with usenet news, unlike email, it is possible to remove
spam that has entered the system, limiting the audience that sees the
message and thus the effectiveness of spamming.
