Email address munging methods

[Greg Boettcher]

I am preparing a research project in which I will be posting a bunch
of email addresses to the Internet to see how much spam they draw. The
addresses will be disguised in various ways, and the project should
help provide data on the effectiveness of those address-disguising
methods. The methods will be as diverse as using JavaScript to
scramble addresses, using CSS positioning to scramble addresses, etc.

But one area where I could especially use more ideas is the kind of
simple munging often done on Usenet. For example:

myn...@domain.REMoVETHiSzz
myX...@domaiX.zz (replace X's with N's)
myname@domain.X, where X=zz
zz.niamod@emanym (reverse letters)

Can anyone think of any other clever examples of this?

Thanks in advance for any help.
