Listserv infiltrators?

Our local peace listserv, which is a Yahoo group, has a "member" going by the name of "Peace25." Peace25 only posts messages with a subject beginning with "URGENT," and they usually request that we immediately contact Congress about something. These frequently have to do with China, generally supporting the Chinese government. The most recent, however, is in support (!) of the Condi Rice nomination.

My guess is that a Chinese government office has created automated "members" of listservs as a way to get their messages out to activist types. I know that many of my readers are members of similar listservs. Do you recognize "Peace25" as a frequent contributor (although never responder) on your listserv? I've also seen one going by "Peace27." E-mail me if you have. Thanks.
