Interesting nontheless. I did have a quick look at the code. For
adding other methods (eg. use an image for the @ or even create an image
for the whole address) we would either need to change the obfuscate
function or move some handling out of this function...

I'd like to get the input of others - especially reusers of this
function (eg. Plugin authors). Do we need better obfuscation? Or can we
live with what we have?

Personally I like to rely on mailserver side anti-spam methods anyway.
Keeping an address secret to spammers is somewhat impossible for a
public address, I guess.
