If a girl is getting a bucket load of positive reviews I would think her client list is going to get larger and that demand is what is going to cause her to up her prices, not the use a of a specific acronym within a review. The more you sell of something that begins cheap, (in this case, a fine ass) the more you end up being able to slowly increase the price.
Look at the McDonalds Double Cheeseburger, fucking delicious, loads sold and they go up like 5p every few months.
