Wow this website is only about a week old and I have already started to get spam on both the comments and via my contact page.
Fortunately I was using the plug-in Akismet that comes with WordPress to catch the comment spam.
Unfortunately though, the WP-ContactForm plug-in did not have anything to try and stop spam.
After a search for “WordPress contact form spam” on Google I found Dragon Design Form Mailer which puts a little verification code that needs to be entered correctly before the email can be sent.
Hopefully this will stop the spam at the gates.
