A man who wrote fake reviews about Italian restaurants and hotels on the online travel site TripAdvisor has been jailed for nine months and ordered to pay an 8,000 euro (9,300 US dollars) fine, the company said on Wednesday.

TripAdvisor said in a statement that the sentence was handed down in June by a court in the southern Italian city of Lecce. There was no immediate confirmation from the court.

The man, who was not named, offered to sell glowing reviews to businesses across Italy to bump up their ratings on the TripAdvisor site, which claims hundreds of millions of online visitors each month.

"We see this as a landmark ruling for the Internet," TripAdvisor said. "Writing fake reviews on TripAdvisor has always been a violation of the law in many jurisdictions... However, this is the first time we have seen the laws being enforced to the point of securing a criminal conviction."

The US-owned company said it believes some businesses paid for fake reviews and were subsequently hit with penalties that lowered their all-important popularity rankings.
