This is already happening, IF they get disqualified for doping (see Shobukhova and Jeptoo).
Unfortunately that does not go back to the races won (or placed in) before they got popped (see Kiprop and Houlihan). They even get to keep their records and medals.
I am with Flanagan here:
Let’s say someone is working at a bank and they embezzle a bunch of money. The bank says, hey, you embezzled a bunch of money, so we’re going to fire you. You can’t work here anymore. But in, like, five years you can come back. We’re not going to get the money from you. You can keep the money. So you get, like, a five-year vacation. To me, these athletes need to give back the money that they stole from the other athletes and I believe that all the accolades should be erased from that day forward. They should not have any accolades to go with that.
