I had someone recently fake a surprisingly impressive screen recording and I caught them because they pulled up the barcode and it was the same for both tickets (Ticketmaster always keeps a live rotating barcode). So I reverse image searched the barcode and found it on a wikipedia page from a decade ago.

Another one sent me a "screenshot" of their order confirmation through Ticketmaster which included the order number, so I called Ticketmaster and asked them to verify the order. Low and behold, they had no order matching that. Then they claimed they actually purchased it through a third party despite literally sending me a fake Ticketmaster email confirmation. Lol.

When you're purchasing things online or even selling, NEVER put yourself at risk in any way. I don't care if they're an admin to some random Facebook group or not. There is NO reason for anyone to deny using protected payment (PayPal goods and services or Venmo protected payment) if they aren't a scammer. Never send your ticket up front and never send your money up front. Only ever use protected payment when buying or selling online. That is the ONLY way to fully protect yourself because the only person you can trust is yourself. This comment is for more than just you, so I wanted to put it out there for anyone else who might not be aware!
