Akismet Worst Offenders plugin
Ever wanted an easy way to sort through all of that spam caught by Akismet (just now, I had to look at 175 spam comments since yesterday)?
Akismet Worst Offenders plugin is just for you. It groups your suspected spam comments by IP address or web site. Then a delete button allows you to easily delete those bulk spam comments right away.
The results are a lot less spam comments to filter through, which allows you to make sure no legiminate comments are captured by accident.
Fantastic plugin and I imagine it will become part of the regular Akismet plugin very soon.
