Kim barely won the short program Wednesday but lost to Sotnikova by more than five points in the free skate the next day. Many in Seoul believed the Queen did enough to keep her crown.
"Sports competition is something that has to be fair and square," said Kim Choong-nam, 70, a retired professor, in Seoul. "If it's felt that the judging is unfair, I believe that it goes against the principles of the Olympics."
Allegations of unfair judging in Sochi were among the most popular searches on major portal sites in South Korea, one of the world's most wired nations.
IOC spokesman Mark Adams called this matter over the judging a "purely hypothetical thing." He said any formal complaint would have to be made with the International Skating Union.
"I'm certain there hasn't been any complaint," he said from Sochi. "If it does, that would be the first step to go through. If there isn't a credible complaint, then we wouldn't take it any further."
After winning gold in Vancouver four years ago, Kim left competitive skating for a year, prompting speculation she would not attempt to skate in Sochi. But Kim returned for the 2012-13 season and won her second world title.
Kim will skate in a show in South Korea in May but otherwise has no plans. She will skip next month's world championships in Saitama, Japan.
Kim has said that her mindset was such in Vancouver that she would "die for gold." That passion was missing in Sochi.
"The motivation was a problem, I think," she said.
Still, she remains South Korea's only Olympic champion in figure skating.
"I actually expected her to win the gold medal because her performance was clean," said Yun Hyo-jung, a 22-year-old university student. But, whatever the medal, Yun takes a longer look.
She "made us really happy," Yun said. "And I am thankful for that."
