Both of these techniques rely on javascript, which means they both have the
same weakness: when spammers "determine" that enough people are doing this,
they'll simply include "javascript resolution" to their bag-of-tricks --
i.e., they'll simply execute the javascript to get the "decoded" output and
parse the resulting HTML.
