How do foreigners interpret Korean comments? Can anyone teach me how to spot the red flag?

Hi everyone! I'm Jiaqi from Taiwan. I'm thinking of getting some treatment in Korea, but honestly, my Korean isn't very good, and I can't understand any of the reviews and comments. I was wondering if anyone could share how, as a foreigner with limited language skills, I can judge whether a clinic's reviews are trustworthy?

I'm currently using translation software, but sometimes the translations sound strange, and I'm not sure if I've captured the key points. Has anyone encountered any reviews or warning signs that seem suspicious? For example, should I be wary of comments that sound like overly promotional posts? Or are there any comments that are generally considered problematic?

I'm actually quite afraid of making a mistake, so I'd like to hear from experienced people how they do their research. Would anyone be willing to share how they filter information? Or recommend some reliable verification methods? Thank you all!
