form spam prevention

[stubarny]

Hi,

I'm looking to set up a jobsboard on my website and have bought a script to handle the applications through a form. The script prevent the form being hijacked for bulk email but there's nothing to stop robots making repetitive spam postings unless I insert a captcha code which will obviously slow down users.

So the question is if i don't use a captcha code do you think there's much of a risk of having spam through these forms? I've noticed kijiji.com requires captchas on its advert reply form but totaljobs.com (a large jobsboard in the UK) doesn't use captchas - how do they prevent spam problems or do you think they accept a small amount of spam will happen and think its not worth inconviniencing users with captchas to prevent the spam?

Thanks for your views.

Regards,

Stewart

Open forms on the web is a bad idea, and SPAM will become an issue if the board becomes semi know
