Web spammed

Funny, this last week I've been actively researching an update for the site, using CAPTCHAs so that I can get my feedback page back online without the form-spam I had been getting. I thought I wasn't going to have to consider implementing it for my blog comments because I've fortunately not gotten all that much comment spam, but then I get another on this entry today. So now I'm wondering if California has anti-spam legislation, and whether I can invoke it in this case.
