Your idea sounds good, but some people have issues with Javascript,
and I'm not sure if it would work well in an RSS feed. It would also
be a bit harder for me to handle internally, given the complicated
way I've coded certain things.

What I've done, is knock out one character from the domain name
and replace it with '?'. This will make the address unusable.
If you aren't sure what the missing character should be, you
can check a previous post by the same person, since I choose
the missing character position using rand().
This additional protection only applies in address fields. 
Elsewhere in the body of a message, you will just have at-sign 
replaced by " at " as before. 

Obviously a human spammer could figure out the missing character,
but the economics of spamming require automated pick-up of
thousands of addresses. If the spammer has to manually repair 
one address at a time, it's not worth it.

I guess I'm going to also have to tweak the hash function that
determines the color and font for people's names.
