X, formerly known as Twitter, has introduced a Handle Marketplace, allowing Premium Plus and Business subscribers to claim or purchase inactive usernames. This move aims to generate revenue as advertising income declines, with prices for rare handles ranging from $2,500 to over $1 million. However, the marketplace has faced criticism for its lack of transparency, particularly in defining inactive accounts and pricing strategies. Concerns have also been raised about user rights and control, following past incidents of forced username reassignments.
