Spam is not a command; rather it is the word used to describe the
situation when text is rolling up on your screen faster than you
can read (or comprehend) it. Spam can be controlled with the use
of the /more command when using the client tinyfugue.
It should be noted that "spam" refers to _useless_ information.
If one goes idle in Town Square in the middle of a conversation,
one ought to expect to come back to screens-full of text. This
is NOT "spam" -- and it is the player's own fault!
