Add option to disable reporting on node delete

I have Mollom installed on a site that protects the 'contact' and 'forgot password' forms. I don't need to protect node forms as Anonymous users (and Authenticated users for that matter) can't create nodes (and only Administrators can create user accounts). Therefore, there's no way nodes are going to be spam.

It is therefore annoying and slightly confusing for my client to see a 'Report as…' message every time he deletes a node.

I'd like to have the option to disable this reporting feature on a per content type/entity basis to allow for my situation as above.
