Spam in moderation "reason" field

You gotta love the spammers. I've installed the comment moderation feature and while I don't have spam in the comments themselves, I'm getting a lot of "report this post" postings with spam in the "Reason" field.

The screenshot shows some of the spam, but that goes on for three or four full screen-loads.

Crazy people. Before I delete these posts, is there anything you need from me for future testing or debugging?
