The spin serve in badminton, where players add pre-spin to the shuttlecock before contact, has proven to be highly effective—so much so that it was deemed "impossible to return" and was banned by the Badminton World Federation (BWF) in 2023 until after the 2024 Paralympic Games. This decision was made to prevent concerns about unfair advantages and to avoid making international tournaments a testing ground for the serve, similar to the previously banned "Sidek serve." Recent
