im not shocked that you get a lot of spam as you publish your full email address on your website Tony.
Email spambots collect email addresses from the net in order to build mailing lists for sending unsolicited e-mail or spam. Such spambots are web crawlers that gather e-mail addresses from Web sites, newsgroups, special-interest group (SIG) postings, and chat-room conversations. Because e-mail addresses have a distinctive format, spambots are easy to write.
