@Anonymous Why would his reviews be hidden? I've had guests before who had been members for years with no reviews, but when I questioned them, it was either because they'd joined with the intention to travel, but their travel plans fell through, they had stayed a couple places but th host hadn't left a review, or they had stayed in Airbnb's but with their spouse and the reviews were under the spouses name and account. (They all turned out to be good guests)
People who start out asking for a discount are bad news- they are being insulting because they are basically telling you your place isn't worth what you're charging. Guest's financial situations are not our concern- if he wants a cheaper place, he should look for another listing.
