But the IOC does that if an athlete tests positive during the event.
In baseball with these records we don't have that. Like, Sammy Sosa maintains he never failed a drug test. We just have MLB saying he tested positive in 2003.
Mark McGwire admitted to a decade of steroid use (bless his soul).
Bonds says his trainer gave him steroids without telling him. He did not test positive in any official in-season, MLB testing. I believe his positive tests were like, adjacent to or within other legal proceedings and the chain of custody on them is super questionable?
So we all know they all did roids
So it's like a Florence Griffith-Joyner situation. Her womens 100m WR still stands but it predated regular Olympic drug testing (1988) and many people think she roided the year she set it. But she didn't test positive in 1988 so that's still her world record.
