I was looking at the reviews on accor.com and noticed they actually show some reviewer full names.

On the reviews, they also show the management responses that are emailed to the customer. Looks like there's no guarantee that the customer name is removed from the response before it's published.

Checked the latest three hotels I reviewed, my name was either shortened or replaced by the review nick, but on all three hotels there was at least one customer name visible. Alerted Accor fb team a week ago, but got no response - so don't really think they take this too seriously even if they claim "You can enter a nickname and no other personal data will be displayed." on the review pages.

First names were often visible, btw, but don't think that is too bad.
