Yep.  It's obfuscation via an XOR with a key included
in the href.  So if you do not want to run javascript,
you can grab the href, pull out the key, xor the
remaining obfuscated string with it and you get the
address.

I.e.:

for email in $(curl https://archive.nanog.org/list | sed -n -e 's/.*cfemail="\(.*\)".*>/\1/p'); do n=0; for b in $(echo 
"${email}" | sed -e 's/\(..\)/\1 /g'); do if [ $n -eq 0 ]; then key=$b; else printf "\\$(printf "%o" $(( 0x${key} ^ 
0x${b})) )"; fi; n=1; done; echo; done

It's all so obvious, isn't it?
