The wild thing is his profile was a random old man with an American name, and the typos and mannerisms tracked with a weird old American man, but looking back I realize he had no pictures of his previous work then suddenly produced some because he did a google image search.
Also, Jesus Christ these scam operations are far reaching if they can hit even private Facebook groups for a single friggin lawnmower on someone's first post.
Facebook has a much bigger scam problem than I thought.
