My vote goes to Uncle Bob. The man seeks out SP's from agencies / indys not as popular as the mainstream ones. Plus he does give negative reviews when warranted.
The final votes have been tallied but you make a good point. I haven't written a negative review (accept for the two girls that stood me up - one in Vegas and the other in Montreal) since 2013. I think the reason is I try not to TOFTT anymore. I see the girls that everyone is raving about, I listen to PMs, and I talk to the booker. My last Montreal Abortion back in 2013 was a girl that had been raved about but had lost interest in the job....and she got a well deserved bad review.
Bob is more like a NEw York restaurant critic. He likes to seek out untested waters and write about them. If you are "sizzilin on a shoestring budget" and you like to venture into the "wild west" and that is what Backpage is - Bob is your man.
