This is Roland from Mosso and I can help with this issue. The problem comes from the code not knowing that it is now on a Clustered hosting solution. To fix the ip issue do a search in your all of your wordpress files for this snippet of code:
$_SERVER['REMOTE_ADDR'];
Replace it with this code:
$_SERVER['HTTP_X_CLUSTER_CLIENT_IP'];
This code swap will allow the wordpress script to obtain the correct IP address of your commentors.
Come into live chat for help if you run into any snags along the line.
