I am working on my school's webpage and need to do a page that has contact info Name/Email/Phone for our staff. Is their a safe way to do this without embeding the email in the html (so bots can't find them and spam us?) I have created a list in flash which bots cant find, however, my menu gets messed up in some browsers.


Any easy safe way to have a contact page without getting spammed? any modules?


thanks!

Easy and safe? Not really.

If you want a 100% safe way for the emails not to be harvested by bots, you'll need to never publish them publicly. Two ways to acheive that, none extremely easy, but still not very hard to do :
  • The "we'll call you back" method. A form where people who want to contact your staff leave their contact info instead of you giving yours.
  • The "captcha" method. To see the list, the visitors need to type in randomly chosen characters displayed as a distorted image.
I've been using the first method for more than 4 years now. Nobody on the list got spammed. Never.

I don't like the second method, because not everybody has perfect sight.

Would anyone be able to explainmore abotu The "captcha" method? I have seen this, but once they type in the distorted word, doesnt it just take them to a html webpage with the email addresses on it? So why cant the spiders located the mailto: on that page?

Sorry, but all the email harvester I know can easily read javascript and hex encoded email adresses. Also, I find really funny to see many people thinking their emails are safe just by writing them those ways:

someREMOVETHIS@email.com
some [at] email [dot] com

It's a child play. It takes only a single line of PHP of code to harvest those.

Wikipedia wrote:Image
This CAPTCHA of "smwm" obscures its message from computer interpretation by twisting the letters and adding a background color gradient.
but once they type in the distorted word, doesnt it just take them to a html webpage with the email addresses on it? 
To access the next page, the bots must be able to understand the image, which most bots can not do because they lack advanced optical character recognition. They simply cannot type in the distorted word since they are not able to extract the letters from the image.
Wikipedia wrote:CAPTCHAs based on reading text — or other visual-perception tasks — prevent visually impaired users from accessing the protected resource. However, CAPTCHAs do not have to be visual. Any hard artificial intelligence problem, such as speech recognition, can be used as the basis of a CAPTCHA. Some implementations of CAPTCHAs permit users to opt for an audio CAPTCHA.
