What’s very cool about this deal from an anti‑spam point of view is that Yahoo is auto‑enabling Akismet for all their customers with a site‑wide API key. This means Akismet is just automatically on without having to sign up for a WordPress.com API key, and every Yahoo customer has the equivilent of a Pro‑blogger Akimset License. That’s a $5/mo value.
We think this really sets them apart from every other host out there, which invest huge amounts of money into email spam blocking but completely neglect comment and trackback spam, leaving you vulnerable and unprotected. Cheers to Yahoo for leading the pack on this one.
