It still works but some anti virus programs hate it. at the end of the day its a cheap tactic, its the same as a html link
what about this, what if you made a pluggin for WP for example or joomla, drupal, PHPBB, opencart... which puts 1 line of code in the footer as well as something valuable so people download it.
this line of code 'imported' in the file contents for a file on your server (php get_file_contents)
this is a much better solution you then have total control over this link, or iframe or whatever you want to put there.
and the best bit is you can put it in the user agreement for the people who download your pluggin. "there may be data from time to time that is inserted into the website" - add that somewhere in a 19 page legal document no one reads and your golden.
a much more scaleable idea that is risk free and bull shit free.
