  1. Captchas don’t work. And they are a pain for users. I’ve developed a proven technique, and it works in WP Contact forms and other PHP pages. It is free to use (open source), and I have found that form spam just stops dead when I implement it on web sites. All free, no ads, and I delete any emails I get requesting information. It’s all here brightverge.com and gocime.com. The technique works.,,,,,,,
