I found another Poshmark store using my photos—what should I do?

So I just stumbled across another seller’s closet and couldn’t believe it… they’re using MY photos to sell similar items! I put a lot of effort into my listings, so seeing someone else use them feels really frustrating and unfair. Has this happened to anyone else? What’s the best way to handle this? Should I report it to Poshmark or try reaching out to the seller first? Any advice would be super helpful!
