Over time I've noticed I have found a nice handful of guys who see me regularly, and some write the review after the first date. Some don't write it until after the first few dates, or wait until after an extended date. Others ask for discounts and "hold" the review until you give in, so that may be why no review were written lol.
Some ladies take breaks, etc. One thing that has helped me when reviews hadn't popped up for a while is to continue a presence online to dissolve any worries of account hacks, etc.
Looking at some profiles, it seems to me, and I could be wrong, that over time as a lady has been in a certain area for a good chunk of time, the reviews slow down - again, which may be due to her building a base of returning gents.
There are guys who see, but don't review certain ladies for fear an ATF will find out he saw direct competition. Kind of sucks for them, but understandable if they want to keep the peace and have privacy.
But an internet presence really helps. I know a lot of people hate twitter, but it has been a great tool for me to keep people updated with any changes, selfies, (to confirm professional photos,) and to keep the conversation going.
