I was in the Marriott forum & noticed a "review" icon on a thread. Click on the thread & it shows a review for 47 Park St. I stayed there many years ago, so clicked on the review - to find it was lifted from the Marriott thread & the review was from 2003 - 12 years earlier. And it's for a property that, while bookable on the Marriott website, does not earn points or allow you to redeem points.

But it was pretty ridiculous to see a review from 12 years ago listed

Cheers.
