I've had ladies tell me it does. One agency lady 6 years ago, of whom i did a TOFTT (her first review, very positive)- said her bookings went up noticeably. A couple others said similar things that the good review helped. The one or two 'meh' reviews did not stay in touch so i did not know if it helped or hurt her biz.
Many years ago, (2004), there was an East Indian new-to-the-business Escort named Sitara. A guy using the handle kinky_boy_70 wrote a positive review of her with his first post here, and several members immediately branded him as a shill. I don't think he made a second post.
(Well, he's banned, so I guess he made at least one additional post).
I saw her, in part based on his review, and wrote a mostly positive review, and she was very busy for the rest of the six months or so that she spent in The Industry, (she was saving money for school tuition).
Sitara, (her handle was "Sitara TRZ", as she had pics on
The Red Zone), also used this board well, replying to reviews, (I think she purged all of her posts when she retired), and attending TERB parties.
I don't think reviews matter much to established Indy Escorts, but they do matter to new Agency ladies. I don't doubt that the Agencies that advertise here read all of the reviews of their new girls, if not the others.
