I've come across the error message several times of

Provider Not Found!
Provider information is no longer available on TER.

I always took that to mean the provider had been delisted, either by request or choice of TER staff. So I'd give up looking for her anymore and move on to searching out reviews for someone else I might like to see.

I've since discovered that one of the reviews I was looking for did in fact exist, but just in a different place, as the ID for the provider had changed. I'm guessing that perhaps there were mistakenly two separate profiles that then got combined into one. But the links to the one that got switched are not updated. So I've potentially missed out on some well reviewed ladies.

I guess this is just a suggestion for anyone else not to take it as a given as I had that a Provider Not Found automatically means a delisting of her profile.
