I read a great idea here a while ago where this webmaster incorporated an invisible field for someone to put there website or some other item. Viewers couldn't see that field so of course it wouldn't be filled in. This was the cue that the form was not from a robot spammer. The robots would see and fill in the invisible field for 'website' or whatever and when submitted the form would of course not go through. This is something I would like to incorporate on my contact page. If someone knows how to do it let me know please.

Mysterious Ways - Hide Email Addresses from Spam Harvesters but I'm getting a bunch of spam which makes me think that spam harvesters know how to decode now.
