Saffers should be on a final warning - if another player gets done for ball-tampering, he's banned for a year, the captain is banned for a year, the coach is banned for a year.
Once is stupidity, twice gets you watched verrrrrry closely, three times - you're gone, mateys.
It's not the same person each time which leads you to believe it's a team policy to help Steyn get more reverse. The skipper should definitely be on the carpet.
