Twice its happened, I left a review and got this message:

Hi there,

Your review has been placed on hold for now as it seems that the location in the review doesn't match that of the escorts tour.
Could you please confirm the time and date of the booking and also the correct location which the booking took place?

Thank you,

Ethan

The problem is, there is no way to edit a review that I can see.
