Are people idiots or do they just not possess equipment capable of
trashing 92 byte icmp traffic and letting the small amount of normal
traffic through unhindered? They are raising freakin' complaints from
users who think the Microsoft ICMP tracert command is just the end all,
be all and is of course completely WRONG with rate-limiting in effect.
