How to avoid ghost doctors, are there signs to look out for?

[kpopkelly]

I am paranoid about ending up with a ghost doctor. I have read horror stories online and while I know it is more rare now as Korea is cracking down on a lot of these fake docs, I am still concerned. Are there signs to look out for, like red flags and such to let me know a doctor is not legit? I read that it was estimated around 100,000 people were victims of ghost surgery between 2008 and 2014 alone. I have for sure already decided to get my work done in Korea, I just want to narrow down my options and make sure I don't have any regrets.
