Spam really sucks. It’s bad enough that email spammers hog up our Internet bandwidth and our mailboxes with spam email, but now they’ve been after web forms. I maintain numerous web sites, with many containing contact forms and the like, so now I have a load of work to do to increase the security level on them. I’ve already added security using a free CAPTCHA service, which works fairly well, but downloads a little slowly. Does anyone suggest any others, or have a good PHP resolution to this issue?
