A very common practice for spammers is to crawl websites trying to find email addresses in the page text, so they can uses those addresses for sending spam. A nice way to block them is to write the email address using an image.

You can create an image with your email address or any other text using Fireworks or even Microsoft Paint. Also, there’s a simple website that helps you if you are not familiar with these tools. ImageFromText is a page where you can write some text, choose their font, color, size and background and quickly generate the image with the desired text.

Images are generated in a PNG file that you can download for free. Nice site!
