Yes--it is a bot, like HipCrime, used generally to
disrupt groups. The content is usually nonsense, as
this seems to be. Normally the poster will hijack an
open server and munge his headers so that he cannot be
traced. Best to ignore it I think. (They
usually come in the hundreds, so we're lucky so far.)

Was there more than two?  Looks like someone is testing a bot. Years
ago in another group I read, my initiation into Usenet involved
HipCrime. Posts by the hundreds of thousands. Hard to filter out,
too.  lol God I love Usenet. :)
