A scammer selling a Google service for which their is no affiliate program?
I wouldn't file this one away due to having a Google crawler on an IP address that’s on the same B block (that's like having the same car brand, not the same make/model)... An IP address that's not even related to the original investigation, but to some anecdote at the very end of the story.
We need more info about the service being sold, and how it's being sold, who's the billing party, etc.
