I've run the site in question for over two years and only yesterday started getting a lot of spam via the contact form (I've had the same forms up since the start).
I tried putting adding the captcha code, which works when I test it but I'm still getting these spam emails.
I've also set two field as required. When I receive these spam emails that come from the form, the two required fields are not included in the information.
Does anyone have any tips on how to stop this ?
