Don't want my support email to get bot spam. Should I use a CAPTCHA script on my web site from a "Contact Us" link? Writing "contact us at support at mywebsite dot com", seems inconvenient for the visitor. Any good suggestions? If CAPTCHA is your suggestion, can you recommend an easy to install script? Thanks.
You could try making the email link encrypted. Google for some sites to do it. You just add email and it makes it so bots do not read it and it still works fine.
Whatever you do is going to have to be a balancing act between usability and security. As one goes up the other goes down. Personally I would suggest using a contact form so that your email address is not visible for harvesting and thats it. If you start to get spam via the form then consider making it more difficult for users by adding CAPTCHA scripts etc. Our CAPTCHA script (.Net) reports on failed attempts along with a number of other techniques we use to detect bots and not one of the many client sites we have create has ever been hit by bots and yet almost all have had users abandon using their form (contact/ sign up/ order) because they failed captcha validation
I often have trouble reading those things. The one here at DigitalPoint is almost impossible for me to read-- I often need 4 or 5 tries to get it right. The one on wikipedia is pretty easy on the eyes, though, and they spell nonesense English words, so people tend to get them right even if they can't see all the letters very well.
