Scalpers, also known as resellers, ticket touts or black-market traders, are individuals or groups who buy tickets or other goods with the sole purpose of reselling them at a higher price. This practice is illegal in some countries and is generally considered unfair as it limits access to events for fans and leads to inflated prices. Other synonyms for scalpers include gougers, profiteers and hucksters, all of which imply someone who unfairly exploits market demand. Recently, new technology such as blockchain has been used to combat scalping and protect consumers from overpriced tickets.
