Sorry to disappoint people who thought this was good advice, but the original poster does not understand what "email obfuscation" is!
Email obfuscation is not doing things like changing the "@" to "at" and so on. Email obfuscation is encoding the entire email address (including, if you are bright, the "mailto:") so that in the HTML there IS no email address. Simply some javascript or jscript which, when the page is compiled by the browser, displays an email address to the person viewing the webpage. Bots can't find it because it doesn't exist in the HTML code. But people can read it just like any other email address and click on it or select it and copy it - because the browser has interpreted the script to display the email address.
Yes, eventually bots could be coded to decipher this, but when there are so many plain email addresses out there, why would they bother?
I personally use my own encoding script which generates some random numbers to create the code and it's deciphering code. But if you want to read about obfuscation and even create your own obfuscated email HTML/script code, try this link: http://www.u.arizona.edu/~trw/spam/spam.htmand the subpage: http://www.u.arizona.edu/~trw/spam/spam.htm (thanks to Tim Williams of The University of Arizona!). That page explains how the page obfuscates. Add some clever stuff to your own script like random numbers being used to multiply and add/subtract and using more than one character code (or just use something other than ISO-Latin-1) so that the bots aren't even going to harvest you even if they are re-coded to interpret that particular obfuscation method. As shown on the websites I have linked you to:
"Your email will appear as 60, 97, 32, 104, 114, 101, 102, 61, 34, 109, 97, 105, 108, 116, 111, 58, 116, 105, 109, 109, 121, 119, 64, 97, 108, 111, 104, 97, 46, 110, 101, 116, 34, 62, 116, 105, 109, 109, 121, 119, 64, 97, 108, 111, 104, 97, 46, 110, 101, 116, 60, 47, 97, 62 to an email harvesting progam"
After that? Well, why not get your own domain name(s) and have as many aliases as you like so that if one gets compromised, firstly you will know who compromised it or where it was compromised and avoid that person/site and secondly you can delete the email address so that further spam gets bounced by your mail server (you don't even GET the spam to filter out) plus the spammers' software will automatically delete that email from the lists or in any case subsequent spam will get bounced repeatedly without coming near your email client AND will waste the resources of the spammers.
(And for the iPot, may I suggest that in future you, as an EggXpert, should investigate your ideas a little further before posting? What you were referring to was some kind of "veiled speech" system, not "obfuscation"! If you investigate this and understand, I would hope you would add to your little video wherever else it is posted too!)
(In my humble opinion, it's hard to believe anyone giving advice on privacy uses gmail but that's an entirely different level of personal information harvesting! :P)
