This really relates back to the simplicity thing I mentioned in the thread about people changing their user names. We do encourage people to say 'I've already reviewed this escort', but we do have to be sensible as to how much information we can allow on the reviews. Besides, there is a word count that cannot be exeeded. This would also make the (already very busy) review mod's life hard work. They deal with anything from 300-400 reviews a week.
