Mischief
There is a move afoot among many bloggers to try to hijack an upcoming "virtual march for peace." This is a bad idea, for a few reasons. One is that automated FAXes are easily misinterpreted or manipulated by the group that sends them on your behalf. Another is that trying to swamp Washington phone lines is juvenile in the first place, and unnecessarily destructive. Third, because it's just not fair play. The inimitable Diana E. Moon has a better idea.
OTOH, if the phones are going to be jammed all day anyway, then every one of their little "time slots" a pro-war "hijacker" takes to call and tell the President how much she supports him is one the anti-war yahoos won't be able to use.
