Automattic.com was bought (no idea if it was unregistered / acquired) by Matt Mullenweg when he set up the company. He also bought https://a8c.com.

Here in the UK with EE/BT that correctly redirects to automattic.com, but it might not for you depending on your ISP.

The wayback machine shows adult content links prior to the domain being put on sale, hence the blocking.

see also landslide.com - a domain that should never have been reused imo
