Re: Hiding email address from spiders

[Michael Grant]

This may be academic, but be aware that this method isn't actually hiding
the address, simply ascii encoding it. It wouldn't surprise me in the least
if spider don't already evaluate ascii.

I stand by my statement that the most effective (though not elegant) is to
replace addy's with images. The likelihood of a spider also doing character
recognition is much less

Carry on.
