Getting into that kind of loop is what the following part of the
script avoids:

ABUSER=`/bin/grep -x $2 $LOGFILE`
if [ "$ABUSER" == "" ]; then
  echo $2 >> $LOGFILE;

It will only do it once per host.  When it comes to spoofed packets,
isn't that what good firewall rules are for-- catching those naughty
kinds of packets?

This little script is just an instrument for gathering a little
possibly useful information and is meant to fit in with other security 
measures; it's shouldn't just stand alone.
