There is no trouble to enter a valid address, wikipedias has list of zipcodes,
even those new with the extra four numbers, so if a spammer really want to
spam on a site, they have no trouble to get the data needed to fool you.

When talking about spam, should tell you that USA is the country from where
over 50% of all spam is sent from, on second place you find china with almost
40%, so getting rid 90% of all spammers, block all USA and CHINA IP-numbers.
