Fixes #29

Looks fine, but we should change small thinks for the WP Codex, but this is more a global topic, so that we merge it before.

Version has to be changed to 2.7.0 and the conflict has to be resolved, but the PR/feature itself is fine and I would be very happy if we can bring this feature back to the plugin.

I have checked this feature out and tested it a bit. I think too it is good to go. The only thing I was thinking about:

Basically when you do activate this feature without giving a black or whitelist every comment will be spam.

And right now, when the API is not available, all comments will be marked as spam (1713 - 1720):
035e26d#diff-33ae96de74050319957e1ac65615cf29R1713

If we can't reach the API because it might be down, maybe we should let it pass? But for both my points I think you could also go with the opposite view. I just would be a bit more lose here.
[Reviewer mislead. See Sergejs comment below, 🤦‍♀️ ]
