Frequently Asked Questions
Q: Is “No Mercy” based on real voice phishing cases in South Korea?
A: While “No Mercy” is a fictional drama, it draws inspiration from the very real and growing problem of voice phishing (also known as vishing) scams in South Korea and internationally. The drama’s portrayal of sophisticated criminal organizations using technology to target victims reflects actual patterns seen in these crimes. However, the specific characters and revenge plot are fictional creations designed to explore the emotional and social impact of these crimes on victims and their families.
Q: How realistic is the use of deepfake technology for revenge as shown in the drama?
A: The drama takes creative liberties with deepfake technology for entertainment purposes. While deepfake technology is real and continues to evolve, using it for the type of infiltration and revenge depicted in “No Mercy” would be extremely difficult and illegal in real life. The show uses this technology as a dramatic device to explore themes of justice and retribution, but viewers should understand that the technical capabilities and legal implications shown are fictionalized for the story’s impact.
