By the eloquent title of your thread, I'm assuming you are wondering if anyone has seen her recently, to find out if she is still around?....
She's well reviewed, yes. She used to be an advertiser here but has not been around for some time.
This (not advertising) doesn't mean she isn't around; it could mean she isn't currently advertising because she's happy with the amount of business she already has (repeats and new clients).
And the dated reviews don't really mean that either, as most sp's who have been around for a little while do not get tons of reviews once it's been established that they provide great service.
Her site is still active and her contact info still there, so the best way to find out might be to contact her directly...
Though I'm not sure what not having ads on CL has to do with anything.... What's with what?
I'm not trying to be rude, but what exactly is your question? What's with her not advertising on CL? Is that the question?
