This question comes up over and over. I guess it’s because WordPress include Akismet in their version 2 but you can’t actually activate it without the WordPress API Key.
Here’s what you do for that API
- Go to www.wordpress.com
- Sign up for an account there. They make you take up a blog on wordpress.com but don’t worry about it, you don’t have to use it
- Once logged in, go to the menu in the top-left of the page My Account > Edit Profile
- Staring you in the face should now be your API key above your personal details. You can use this on all your non-wordpress hosted blogs to enable Akismet
