Reviews are not necessarily indicative of something "unusual".  Perhaps she has a Twitter on her TER profile you can see if she has been active there, search on the boards using the search tool to see if she has been posting lately, or you can always just email and ask her about it.  I personally have seen a huge decrease in reviews as of late, but everyone is different, there are highs and lows.  Summertime can be fair slow as well.  

Good luck on your quest!

It just means that she is focusing on guys she has already seen

...and the guys she has seen keep booking her up.

It's not even a little bit unusual for a new provider to get a huge number of reviews (once she has crossed that First Review threshold, which can take a while) if she's professional in her approach & meets & exceeds expectations. And it's not unusual for the reviews to taper off to nothing: there's no incentive to update reviews, and many mongers don't write them at any rate. If her cup runneth over with guys she likes who like her in return - repeatedly - odds of a new review showing up diminish.

One aspect of this situation that you didn't mention was the possibility that you'd be wasting your time trying to book with her. This can happen if a provider quietly retreats from providing - for any of innumerable possible reasons. Your best defense against this is by checking her P411 profile, which will indicate the last time she logged in. If it was 4 months ago, you may wish to look elsewhere.

I guess not all guys review so it a hit or miss for $30 bbfs I see you and would review you.

Don't overthink this.

IMO this is nothing out of the ordinary to be concerned about.

Although I've been in the Hobby some time my reviews are sporadic & limited. Most of the niche of gentlemen who book with me want to remain Under The Radar for privacy & discretionary reasons. Each provider, her circumstances & services are different. My best advice is to collect as much info as is available. You can even contact the provider & request where to find all her ad listings & reviews. Most providers don't mind giving you that info. I am always happy to comply when asked. Also nothing beats a live conversation with the provider. It's not only the best way to make inquiries but also get a sense of their personality & if you are simpatico.
