gravatar: force dispaying identicon

Question

Is there any way to force gravatar to always return identicon URL?

The only way I found so far is: ?forcedefault=1&default=myCustomGeneratedImageUrlHere. However I don't want to generate identicon myself.

Any ?forceIdenticon param?

If you're using Wordpress check out this plugin, http://scott.sherrillmix.com/blog/blogger/wp_identicon/

if not, maybe download and try reverse engineer?

Answer 2

I ended up with just using md5(MY_CUSTOM_SALT + $email) as an identifier.
