This may be a bit technical, but I was discussing the idea with xmaddness, so thats what got my brain moving. Yes you could try stuffing the keyword list to carnivore/omnivore in an email header, subject line, or even the body. The problem with this is that any programmer with 1/8 of a brain will make sure any traffic containing 100% of the keyword list will be either deleted, or passed on to a holding place to be reviewed. With that in mind, the range in which messages are actually flagged is unknown, so it could be the 10-35% range, 5-60% or anywhere inbetween. With that said, the system still has to analyze the packets and decide what to do with them, so any message containing a chunk of keywords would have to be checked, which takes away system resources, slowing down the overall process of monitoring email traffic. While that might seem like a good idea, I'm sure giving the current political climate, it could be construted as a Denial of Service attack against a government system, and therefore obstruction of justice. Definately not something I would want to get caught up in.
