Very good

Great plugin.
Been using this for 2 months now and it hasn’t let a single spam comment through.
Very occasionally it will block a legitimate comment though (I’m going to file a support issue about that – I may have an incorrect setting) so you need to check the log of blocked comments just in case.

Suggested improvements:

1) Add the ability to unblock a comment from Reports -> Detailed view.
Currently if a legitimate comment is blocked there is no way to unblock it. I have to manually submit the comment myself using the commenters details.

2) In Reports -> Detailed view, add a filter to only show blocked comments and filter out all login & registration attempts.
Because there are a few false positives, I have to check the detailed view daily to make sure no legitimate comments have been blocked.
Being able to only display blocked comments would make this a much faster task.

Thanks!
