It's important to note that the fee isn't collected at the point of listing; it's collected only at the point of sale. If you choose to list a ticket and in your experience it didn't sell because the market was saturated and perhaps it wasn't priced at a desirable rate, you wouldn't have to pay a sell fee to list on our site.
