The problem is places like support forms. If you go to my site, click on "contact us" and fill in your message and email, you did not directly email me, as per boxbe. So if I honestly try to reply to you, I'll be forced to waste my time? You better believe you'll never get a reply then.

So to reply to your "if people aren't willing to complete a captcha to send me an email, that email is probably not so important for them.". No. Replying to your request isn't that important to me. It probably was to you though....
