So, I have posted a WTB classified about a week ago. I received a direct email (not a private message on FPG) from a user (I will leave unnamed for the time being), telling me that he has the pen that I am interested in. I asked for pictures, he sent me some, then I asked for additional (specific) images and a writing sample, he sent me what I wanted although the second set is not the same pen as the first one. (original pen, he said, is a medium, writing sample says it is a stub. first set doesn't have an inlay, second one does etc.). I did a google search and found out that the first set of pictures come from a website in Singapore, second set comes from a reddit user's posting a year ago.

At what point do I report? What is the process (since none of this is happening within FPGeeks)? I am relatively new, and this user has been around few more months than me. I don't want to damage someone's reputation either.

Suggestions from experienced folks?
