After Brock Lesnar nearly sent himself to the hospital attempting a Shooting Star Press at WrestleMania XIX (arguably, Brock had performed the move repeatedly in developmental, but never before in WWE), the move landed itself on the banned list. The move is already a high-risk endeavour due to being of the top rope variety, but the fact that it’s very easy to either over or under-rotate, combined with an inability to see where you’re landing until just before impact, meant that it had a significantly higher potential for causing injury. Indeed, other wrestlers known for attempting the SSP, notably WCW and WWE Superstar Billy Kidman, often received criticism for being “sloppy” when performing it (Kidman had it turned into a story line where he was afraid to perform the move after legitimately injuring Chavo Guerrero during a match when he drove his knees into Chavo’s neck). Exceptions have been made to this ban over the years, when dedicated performers have proved beyond a shadow of a doubt that they can hit it safely and consistently, including Evan Bourne and, most recently, Neville, whose Red Arrow is an even more complicated twisting version of the move. Additionally, Superstars such as John Morrison have performed a standing version of the SSP, which is significantly safer due to being performed from a grounded position.
