I don't want my ugly mugg on the internet either.  Just read the reviews, click on the links to their ads.

Is there a reliable site that has a greater instance of ads where the girls don't blur their faces? Maybe my tastes are too finicky, but I have yet to see a lady that was all I imagined who's ad didn't show her face. THE best time I've had was with a lady who did show her face in her ad. No surprise at the door. Knew exactly what to expect looks wise. I do realize that my limited budget doesn't put me in the porn star range who do show their faces.

choice to either blur her face or use her hair to cover her face, eyes, or breasts.  I will examine her pictures as best I can and make my decision to see or not to see her.  I have yet to be dissapointed.

I do too. No qualms with ladies who blur their face. The one lady who didn't told me that her ad company recommended she not blur her face as her beauty would help bring business. Completely agree with that. It was a huge deciding factor.
One problem is that looks ratings here are quite subjective. I've seen ladies with 9's that I wouldn't give a 6 or 7 to if I saw them walk by! She had a great body which could add to the rating "butter face"......

What I find weird is when a porn star, whose face is well known and easily findable bobbing up and down on a dick, blurs her face in a provider ad.  Like, what?  You're a porn star but your embarassed about being a provider?  Gimme a break!  I've noticed this several times.

That is funny for a PS to do that.  

No suggestions??
As an example, royalgfeclub seems to have a higher probability of face-showing ladies. Can anyone think of others? Bueller? Bueller?

Where the heck are you located?

There seem to be lots of sites with clear images but YMMV with the reliability of those images. Cityvibe, Eros, etc. have lots of unblurred faces. There are RELIABLE agencies in specific cities or regions that do not blur faces or at least not all faces. And many independents don't blur.

Gotta read the reviews and maybe use tineye. Reviews are sometimes generous or skewed toward the positive but if there's a major problem photoshopped or obscured by the blur, that would probably be mentioned.

Other than providing more information, such as your general location or where (geographically) you'll be looking for services, it is pointless to list dozens of agencies or websites with accurate unblurred pictures that are of no use to you.
