> One fake account winning an auction I was selling then failing to pay

I feel like auctions should be auto-pay. Or, at least have an option to list them that way. This reminds me of the time I was selling football tickets and someone did this. I had to scramble to sell these things after the person bid and never paid.

Tickets are obviously worth nothing after the event. It was a major headache, and I almost didn't sell them at all.
