Concur.  Two reasons, off-hand.

1. Neat way to DDoS site is the hit a few thousand sites with a spoofed
return address.  All thousand sites then go back to one box - which then
dies.  Works with superping nicely.

2. Infinite loop.  Consider the old 'finger' situation.  'nuff said?

Hi,

I wouldn't recommend writing a script to 'automatically scan them back',
for several reasons.  The most obvious reason is that some scans are
simply spoofed. If a script 'automatically scanned them back', it would
be quite easy to get the script to scan innocent sites.
