Thanks to Dataflex I found out another great free online service which helps you fight spam.

As we all know, now and than you want to put your email address somewhere, be it a blog, MySpace or website. In fear of being buried by loads of unwanted and unsolicited email we hide and miss out on some people, simply because we don't want to make our email address public.

But if you want to enable contact with your readers or visitors, you can use one or more techniques I already write about, or you can use a simple as simple can be website: Hyde my Email.

The only thing you have to do is to enter your email address and in a jiffy receive a HTML code you can insert into your posts and profiles. Easy and quick.

Hyde my Email says in its faq:

At hidemyemail we take your email address and encode it. This process makes your email address look like a random string of code rather than an email address. You can then post this encoded address, with a link to hidemyemail.net, on places like message boards, usenet, blogs and myspace without the fear that spambots will pick it up.

For encription of email addresses Hyde my Email uses a system known as base64. If you want to know the address of the person using the service, you have to enter the code on the website and click on 'show email'.
