It is like walking a tightrope here sometimes. There are reviews and there are Reviews. Generally what causes no trouble in the Forum (from my reading over the years) is a statement that you engaged someone, that he looked exactly like you thought he would, that you, the client, had a great time (or not) and that the escort was well worth the money you spent (or not). It seems like you can even say how much you spent but I can never tell. You can explicitly state that you are open to speaking about your experience by PM or it will be presumed by your post. More extensive and explicit reviews will probably be taken down from the Forum but always welcomed in the Review section. Of course, even those can't get really as explicit as in the old days.
