As far as I can see thay are using url/cgi encoding in the email address. This is trivial to circumvent, as is using html entities, or any other reversible scheme.
With a constantly varying algorithm. So they obfuscate, but they never obfuscate in a predictable way. Which means if you're a spambot, you have to look at every byte of every page and attempt to de-obfuscate it in every possible way to see if it's obfuscated. You CAN do it, but you make it computationally massively expensive.
