The OP subject doesn’t look like a scam to me, just incompetent listing - muddled up photos not carefully inspected/selected. Occam’s Razor, people! Sure, be wary of such mistakes as possible indicators of dodginess, but it’s relatively easily checked upon if one is seriously interested. If anything, the vendor also owning an M&E suggests they may actually play/know something about flutes. Yes, the photos could be harvested ones used as part of a scam, but I rather doubt it.
