Quoka classifieds scam. Has anyone ever been cheated by someone who sent an ID card called Robin Leder?

I have transferred money for a Nintendo Switch to a person who is called Robin Leder according to the photo. Now Quoka says that this user is currently being checked as if I was very likely cheated. He didn't answer after that either. I checked the ID number once and it seems to agree. Did someone have a problem with the exact same person or something similar? And maybe. Tips on what I can do?

Depends on how you transferred the money to him. Paypal, bank account?

I made a bank transfer. The money is gone for now but if the ID is real I could show it

Then you should have his IBAN after all? And if the ID card is also genuine (even if not), you should simply create all the data (chat history, IBAN, possibly ID card…) for the police and the ad.

Ok thanks i have to sue the money under civil law or is an advertisement enough?

I'm not sure, but I think both are possible

Ok thanks
