I’ve developed an anti-form spam technique, which I’ve discussed before here and on my Security Dawg site. It works with PHP-based sites (so can work with just about any blogging platform with a bit of customization), and also works with WordPress sites. It’s quite easy to implement, and very effecting in stopping form and comment spammers.
I hadn’t gotten around to installing it here, but today brought a form spammer who was using the Contact form to send me spam. It wasn’t really bothersome, since the spam just goes to my spam folder automatically. And it’s not very effective for the form spammer, since one of their objectives is to make their form spam visible.
But since the form spammer found my site (which is difficult, based on my readership count which could be counted on the thumb of both hands), I decided to implement my anti-form spammer technique here.
That didn’t take long. One file to change (to insert the appropriate email values), three files to upload into the theme folder here, and then editing the Contact page to use the anti-form spammer template. That’s all.
And then a “Huzzah!”
I got things done at 8pm tonight. Before then, there were about 10-15 spams per hour. After that, none. Zero. Zip. Nada. Not one form or comment spam message since then.
As I have mentioned before, it is easy to implement. And very effective. Whenever I put the technique on a site, form spam stops. Absolutely stops.
So, for all of you readers (yes, even you in the back), check out the links above. Or go to my FormSpammerTrap.com site, where you will see what the form spammer sees. Then check out the info page there for details on how to get the code for your site.
And it is all free. No obligation. Open source.
As I say on the FormSpammerTrap site — it just works.
