That’s true. We are discussing the idea of integrating this feature to Antispam Bee (http://de.wordpress.org/plugins/antispam-bee). That’s why it is so quiet here …
If you are looking for alternatives, there are some plugins using the underlying tool:

Or you will be patient and see what is coming in the future. 🙂
All the best,

I have been using this plugin under recent versions of WordPress, up to and including the current 4.7.1 release. I can report that it functions as promised and really doesn’t require any updating at this time.
By the way, I’m the creator of the Comment Blacklist for WordPress as mentioned.
