I see two completely separate issues here. The first is the issue of spam, and the second is the issue of the moderator's edit.
Looks like Spam to me
If a user posts the same answers to different questions, and both are links to a product, there's a good chance it's spam. What's more, the user's website in his/her profile just happens to also be "mafiree.com". Coincidence? I think not.
Okay, so why did the moderator roll back the edit
...but then I noticed it was recently edited by a moderator. Another user had replaced the contents with [content spam deleted pending moderator review], and George Stocker rolled it back.
I'm going to go out on a limb and suggest that George Stocker's edit wasn't intended to say he disagreed with the post being spam. Instead, he was rolling back what is essentially vandalism by the user who edited it with the "[content spam deleted pending moderator review]" message. He can still disagree that it's spam, but regardless, editing a post to destroy it isn't how we make it easier for people to review it, and George was merely fixing that particular issue.
In short, this isn't how we handle spam, editing it and replacing it with a meta-message. This is what flags and comments are for. If enough users agree the content is spam, then it will be auto-removed, without any sort of vandalism or making it harder for people using the review queue to actually review the content as spam.
We actually have to open up the post in a separate tab and look at the revision history to see why it's marked as spam. Which isn't helpful. This makes it harder for regular users to participate in the community process, and means the moderator is most likely going to need to intervene in something that most likely won't require moderator intervention.
With that said, George may not have deleted the post because he wanted to let the community decide. Moderators will do that sometimes if they aren't sure themselves, and that's okay. His decision to not take action doesn't mean he disagrees with any flags.
You didn't indicate if you flagged, and if your flag was declined. If the flag was declined, then a moderator definitely disagreed, but if it's in the review queue, then it's possible George was acting on some other flag or just happened to visit the question from the main page.
In short, don't take the rollback to the edit to mean it's not spam, just that editing out content isn't the way to handle spam.
