The “Anomalies Card” might be one of the most sophisticated among all others. This card allows you to identify which users are trying to game the commenting system, or who are very active for legit reasons.
The value is better understood when each individual filter within the card is reviewed separately. So let’s dive in.
Group by “IP to Emails”
The “IP to Emails” filters counts all the comments that were left from a specific IP address. The number of comments itself is a link to the list of those comments from the same IP address on the “All Comments” page.
For each IP address, the plugin retrieves all unique email addresses that have been used while posting the comment. As you can see in the screenshot below – all 4 comments from the 119.215.190.99
IP address have been posted by users using 4 different email addresses.

This might help you understand who tried to multipost and influence the discussion single-handedly.
Group “Email to IPs”
The “Email to IPs” filter has a reversed logic – it counts and groups comments left using the same email address but from different IP addresses. The number of comments itself is a link to the list of those comments from that email address on the “All Comments” page.

As you can see, a user with the email address daniel@generator.kagg.eu
left 133 comments from a variety of IP addresses. The card shows only the last 10 – otherwise, in some cases, the list may be too long.
With this information, you have much more information to make a decision about whether a certain email or an IP address address should be blocked, or a combination of them.
