Email Obfuscator
Email Obfuscation is a way to avoid address harvesting when publishing an e-mail address online. It doesn't guarentee to stop spam but if used, especially with a combination of other techniques, it can substantially help to reduce spam.
The method used by this tool is to convert your e-mail address from readable text to ASCII characters. This prevents many address harvesters from recognising it as an e-mail address. Type your e-mail address into the box and click obscure, then use the result anywhere (text and in html e.g. mailto links) you need your e-mail address.
