Wesley Barnes, who is a US citizen, had posted several scathing reviews of the Sea View Resort on the travel review site.
He was subsequently detained and charged under Thailand's strict anti-defamation laws. He was later released after issuing a public apology.
Now TripAdvisor has hit back.
The saga appeared to have ended when Mr Barnes left Thailand last week.
But TripAdvisor has had the last word by leaving a warning notice on the hotel's page.
