[thelist] spammers / IP address / specific or wildcard match

I'd be interested to know the answer. However, one problem that springs to
mind is that spamming a form takes just one 'request' (after they've scraped
your form from a different IP) would it be possible to for spammers to spoof
their IP address (as they wouldn't care about the response)? 

If so, denying entire IP ranges could potentially be used against you to
block valid visitors.

Does anyone know if it is actually possible to spoof an IP in this manner?
